In this part, let us pay attention only to Daniel 9:25-26a which covers the 69 weeks of the seventy weeks in the prophecy. This 69 week period is marked by the issuing of the decree to restore and rebuild Jerusalem. However, there were four decrees to rebuild Jerusalem as recorded in the Bible and history. The first decree was issed by Cyrus (2 Chronicles 36:22-23; Ezra 1:1-4;6:3-5). The decree of Cyrus does not fit well with what the prophecy says because the decree covers only rebuilding of the temple and not the city itself.

Daniel 9:25-26a

25 "Know and understand this: From the issuing of the decree to restore and rebuild Jerusalem until the Anointed One, the ruler, comes, there will be seven 'sevens,' and sixty-two 'sevens.' It will be rebuilt with streets and a trench, but in times of trouble. 26 After the sixty-two 'sevens,' the Anointed One will be cut off and will have nothing.

2 Chronicles 36:22-23

22 In the first year of Cyrus king of Persia, in order to fulfill the word of the LORD spoken by Jeremiah, the LORD moved the heart of Cyrus king of Persia to make a proclamation throughout his realm and to put it in writing: 23 "This is what Cyrus king of Persia says: " 'The LORD, the God of heaven, has given me all the kingdoms of the earth and he has appointed me to build a temple for him at Jerusalem in Judah. Anyone of his people among you—may the LORD his God be with him, and let him go up.' "

Ezra 1:1-4

1 In the first year of Cyrus king of Persia, in order to fulfill the word of the LORD spoken by Jeremiah, the LORD moved the heart of Cyrus king of Persia to make a proclamation throughout his realm and to put it in writing: 2 "This is what Cyrus king of Persia says: " 'The LORD, the God of heaven, has given me all the kingdoms of the earth and he has appointed me to build a temple for him at Jerusalem in Judah. 3 Anyone of his people among you—may his God be with him, and let him go up to Jerusalem in Judah and build the temple of the LORD, the God of Israel, the God who is in Jerusalem. 4 And the people of any place where survivors may now be living are to provide him with silver and gold, with goods and livestock, and with freewill offerings for the temple of God in Jerusalem.' "

Ezra 6:3-5

3 In the first year of King Cyrus, the king issued a decree concerning the temple of God in Jerusalem: Let the temple be rebuilt as a place to present sacrifices, and let its foundations be laid. It is to be ninety feet high and ninety feet wide, 4 with three courses of large stones and one of timbers. The costs are to be paid by the royal treasury. 5 Also, the gold and silver articles of the house of God, which Nebuchadnezzar took from the temple in Jerusalem and brought to Babylon, are to be returned to their places in the temple in Jerusalem; they are to be deposited in the house of God.

The second decree was issued by Darius (Ezra 5:9-15, 6:1-6). Again, this decree only covers rebuilding of the temple. Moreover, it is only a confirmation of Cyrus decree previously issued.

Ezra 5:9-15

9 We questioned the elders and asked them, "Who authorized you to rebuild this temple and restore this structure?" 10 We also asked them their names, so that we could write down the names of their leaders for your information. 11 This is the answer they gave us: "We are the servants of the God of heaven and earth, and we are rebuilding the temple that was built many years ago, one that a great king of Israel built and finished. 12 But because our fathers angered the God of heaven, he handed them over to Nebuchadnezzar the Chaldean, king of Babylon, who destroyed this temple and deported the people to Babylon. 13 "However, in the first year of Cyrus king of Babylon, King Cyrus issued a decree to rebuild this house of God. 14 He even removed from the temple of Babylon the gold and silver articles of the house of God, which Nebuchadnezzar had taken from the temple in Jerusalem and brought to the temple in Babylon. "Then King Cyrus gave them to a man named Sheshbazzar, whom he had appointed governor, 15 and he told him, 'Take these articles and go and deposit them in the temple in Jerusalem. And rebuild the house of God on its site.'

Ezra 6:1-6

1 King Darius then issued an order, and they searched in the archives stored in the treasury at Babylon. 2 A scroll was found in the citadel of Ecbatana in the province of Media, and this was written on it: Memorandum: 3 In the first year of King Cyrus, the king issued a decree concerning the temple of God in Jerusalem: Let the temple be rebuilt as a place to present sacrifices, and let its foundations be laid. It is to be ninety feet high and ninety feet wide, 4 with three courses of large stones and one of timbers. The costs are to be paid by the royal treasury. 5 Also, the gold and silver articles of the house of God, which Nebuchadnezzar took from the temple in Jerusalem and brought to Babylon, are to be returned to their places in the temple in Jerusalem; they are to be deposited in the house of God. 6 Now then, Tattenai, governor of Trans-Euphrates, and Shethar-Bozenai and you, their fellow officials of that province, stay away from there. 7 Do not interfere with the work on this temple of God. Let the governor of the Jews and the Jewish elders rebuild this house of God on its site.

The third decree was issued by Artaxerxes to Ezra (Ezra 7:11-26) in 457 B.C. Again, the decree concerns only the rebuilding of temple with law regulating worship in the temple.

Ezra 7:11-26

11 This is a copy of the letter King Artaxerxes had given to Ezra the priest and teacher, a man learned in matters concerning the commands and decrees of the LORD for Israel: 12 Artaxerxes, king of kings, To Ezra the priest, a teacher of the Law of the God of heaven: Greetings. 13 Now I decree that any of the Israelites in my kingdom, including priests and Levites, who wish to go to Jerusalem with you, may go. 14 You are sent by the king and his seven advisers to inquire about Judah and Jerusalem with regard to the Law of your God, which is in your hand. 15 Moreover, you are to take with you the silver and gold that the king and his advisers have freely given to the God of Israel, whose dwelling is in Jerusalem, 16 together with all the silver and gold you may obtain from the province of Babylon, as well as the freewill offerings of the people and priests for the temple of their God in Jerusalem. 17 With this money be sure to buy bulls, rams and male lambs, together with their grain offerings and drink offerings, and sacrifice them on the altar of the temple of your God in Jerusalem. 18 You and your brother Jews may then do whatever seems best with the rest of the silver and gold, in accordance with the will of your God. 19 Deliver to the God of Jerusalem all the articles entrusted to you for worship in the temple of your God. 20 And anything else needed for the temple of your God that you may have occasion to supply, you may provide from the royal treasury. 21 Now I, King Artaxerxes, order all the treasurers of Trans-Euphrates to provide with diligence whatever Ezra the priest, a teacher of the Law of the God of heaven, may ask of you- 22 up to a hundred talents of silver, a hundred cors of wheat, a hundred baths of wine, a hundred baths of olive oil, and salt without limit. 23 Whatever the God of heaven has prescribed, let it be done with diligence for the temple of the God of heaven. Why should there be wrath against the realm of the king and of his sons? 24 You are also to know that you have no authority to impose taxes, tribute or duty on any of the priests, Levites, singers, gatekeepers, temple servants or other workers at this house of God. 25 And you, Ezra, in accordance with the wisdom of your God, which you possess, appoint magistrates and judges to administer justice to all the people of Trans-Euphrates—all who know the laws of your God. And you are to teach any who do not know them. 26 Whoever does not obey the law of your God and the law of the king must surely be punished by death, banishment, confiscation of property, or imprisonment.

The fourth decree was issued by Artaxerxes to Nehemiah (Nehemiah 2:1-8). in 444 B.C. This decree fits well with the decree mentioned by angel Gabriel in Daniel 9:25 for this decree covers the rebuilding of the city. Moreover, Ezra recorded that the rebuilding was done under persecution and trouble (Ezra 4:12-13, 23). Therefore, it is reasonable to conclude that this is the decree that marks the beginning of the seventy week prophecy. According to Nehemiah 2:1, the decree is issued in the month of Nisan in the twentieth year of King Artaxerxes. We know from history that King Artaxerxes's father died shortly after December 17, 465 B.C. and Artaxerxes became King of Persia after his father. However, we need to take into account the custom of Persia which viewed that a year was Nisan to Nisan (March to March in our calendar). In addition, the first year of a king is the month of Nisan following the partial year of succession. Therefore, in king Artaxerxes's case, his first month of kingship was Nisan, 464. Without a specific alternative date, it is reasonable to assume that first year of king Artaxerxes started on Nisan 1, 464 B.C. and the twentieth year of his reign was then Nisan 1, 444 B.C. which can be translated into March 5, 444 B.C. in solar year calendar. From our previous study, we concluded that Jesus was crucified on Nisan 14, 33 A.D. (Friday, April 3, 33 A.D.). Moreover, the prophecy delivered by angel Gabriel aslo mentions the project of rebuilding will take place in times of trouble. This indeed fits well with the actual situation as recorded by the project manager, Nehemiah (Nehemiah 4:6-12). People near Jerusalem tried not only to stop the project, but were ready to attack and kill the workers.

Daniel 9:25

25 "Know and understand this: From the issuing of the decree to restore and rebuild Jerusalem until the Anointed One, the ruler, comes, there will be seven 'sevens,' and sixty-two 'sevens.' It will be rebuilt with streets and a trench, but in times of trouble.

Nehemiah 2:1-8

1 In the month of Nisan in the twentieth year of King Artaxerxes, when wine was brought for him, I took the wine and gave it to the king. I had not been sad in his presence before; 2 so the king asked me, "Why does your face look so sad when you are not ill? This can be nothing but sadness of heart." I was very much afraid, 3 but I said to the king, "May the king live forever! Why should my face not look sad when the city where my fathers are buried lies in ruins, and its gates have been destroyed by fire?" 4 The king said to me, "What is it you want?" Then I prayed to the God of heaven, 5 and I answered the king, "If it pleases the king and if your servant has found favor in his sight, let him send me to the city in Judah where my fathers are buried so that I can rebuild it." 6 Then the king, with the queen sitting beside him, asked me, "How long will your journey take, and when will you get back?" It pleased the king to send me; so I set a time. 7 I also said to him, "If it pleases the king, may I have letters to the governors of Trans-Euphrates, so that they will provide me safe-conduct until I arrive in Judah? 8 And may I have a letter to Asaph, keeper of the king's forest, so he will give me timber to make beams for the gates of the citadel by the temple and for the city wall and for the residence I will occupy?" And because the gracious hand of my God was upon me, the king granted my requests.

Ezra 4:12-13

12 The king should know that the Jews who came up to us from you have gone to Jerusalem and are rebuilding that rebellious and wicked city. They are restoring the walls and repairing the foundations. 13 Furthermore, the king should know that if this city is built and its walls are restored, no more taxes, tribute or duty will be paid, and the royal revenues will suffer.

Ezra 4:23

23 As soon as the copy of the letter of King Artaxerxes was read to Rehum and Shimshai the secretary and their associates, they went immediately to the Jews in Jerusalem and compelled them by force to stop.

Nehemiah 4:6-12

6 So we rebuilt the wall till all of it reached half its height, for the people worked with all their heart. 7 But when Sanballat, Tobiah, the Arabs, the Ammonites and the men of Ashdod heard that the repairs to Jerusalem's walls had gone ahead and that the gaps were being closed, they were very angry. 8 They all plotted together to come and fight against Jerusalem and stir up trouble against it. 9 But we prayed to our God and posted a guard day and night to meet this threat. 10 Meanwhile, the people in Judah said, "The strength of the laborers is giving out, and there is so much rubble that we cannot rebuild the wall." 11 Also our enemies said, "Before they know it or see us, we will be right there among them and will kill them and put an end to the work." 12 Then the Jews who lived near them came and told us ten times over, "Wherever you turn, they will attack us."

To verify the accuracy of the prophecy, the calculation is more conveniently done in terms of number of days instead of number of years because there are two different kinds of year in our discussion: prophetic year which is 360 days a year [1] and solar years. For simplicity, we may calculate the number of days between the start and end of the sixty-nine week in terms of modern day calendar which is based on solar year. There are 476 solar years between Nisan 1, 444 B.C. to Nisan 1 33 A.D.. One solar year is equal to 365.24219879 days (this explains why the modern day calendar, the Gregorian calendar, has 365 days a year while adding 1 day to February to a year if the year is divisible by 4 and is called a leap year. But, if a year is divisible by 4 and 100, it is not counted as a leap year unless it is also divisible by 400). Multiplying 476 solar years by 365.24219878, we come to 173,855.28662404 days or 173,855 days [2]. But, 69 weeks is equal to 69 * 7 * 360 days or 173,880 days. There is a difference in 25 days (173,880 - 173,825). Adding 25 days to March 5, 33 A.D. come to March 30, 33 A.D. which was a Monday and is known as the Triumphal entry (Matthew 21:1-11) of Jesus, the Anointed One, into Jerusalem. Jesus was then crucified on April 3, 33 A.D. which was a Passover Friday. Therefore, God fulfilled His salvation plan by sending His one and only son, the Anointed One, the Messiah to become a Passover lamb and died for all mankind so that whoever believes in Him shall not perish but have everlasting life (John 3:16).

Matthew 21:1-11

1 As they approached Jerusalem and came to Bethphage on the Mount of Olives, Jesus sent two disciples, 2 saying to them, "Go to the village ahead of you, and at once you will find a donkey tied there, with her colt by her. Untie them and bring them to me. 3 If anyone says anything to you, tell him that the Lord needs them, and he will send them right away." 4 This took place to fulfill what was spoken through the prophet: 5 "Say to the Daughter of Zion, 'See, your king comes to you, gentle and riding on a donkey, on a colt, the foal of a donkey.' " 6 The disciples went and did as Jesus had instructed them. 7 They brought the donkey and the colt, placed their cloaks on them, and Jesus sat on them. 8 A very large crowd spread their cloaks on the road, while others cut branches from the trees and spread them on the road. 9 The crowds that went ahead of him and those that followed shouted, "Hosanna to the Son of David!" "Blessed is he who comes in the name of the Lord!" "Hosanna in the highest!" 10 When Jesus entered Jerusalem, the whole city was stirred and asked, "Who is this?" 11 The crowds answered, "This is Jesus, the prophet from Nazareth in Galilee."

John 3:16

16 "For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life.
