Introduction:
Cyrus's Decree is a significant event in biblical history, marking the end of the Babylonian exile for the Jewish people and the beginning of their return to Jerusalem to rebuild the Temple. This decree is attributed to Cyrus the Great, the founder of the Persian Empire, and is documented in several books of the Old Testament. The decree is seen as a fulfillment of prophetic words and a demonstration of God's sovereignty over the nations.

Biblical References:
The primary biblical references to Cyrus's Decree are found in the books of Ezra, 2 Chronicles, and Isaiah. These passages highlight the decree's role in the restoration of the Jewish people and the rebuilding of the Temple in Jerusalem.

1. Ezra 1:1-4 :
"In the first year of Cyrus king of Persia, to fulfill the word of the LORD spoken through Jeremiah, the LORD stirred the spirit of Cyrus king of Persia to send a proclamation throughout his kingdom and to put it in writing as follows: 'This is what Cyrus king of Persia says: The LORD, the God of heaven, has given me all the kingdoms of the earth and has appointed me to build a house for Him at Jerusalem in Judah. Whoever among you belongs to His people, may his God be with him, and may he go to Jerusalem in Judah and build the house of the LORD, the God of Israel. He is the God who is in Jerusalem. And let every survivor, wherever he resides, be assisted by the men of his region with silver and gold, with goods and livestock, along with a freewill offering for the house of God in Jerusalem.'"

2. 2 Chronicles 36:22-23 :
"In the first year of Cyrus king of Persia, to fulfill the word of the LORD spoken through Jeremiah, the LORD stirred the spirit of Cyrus king of Persia to send a proclamation throughout his kingdom and to put it in writing as follows: 'This is what Cyrus king of Persia says: The LORD, the God of heaven, has given me all the kingdoms of the earth and has appointed me to build a house for Him at Jerusalem in Judah. Whoever among you belongs to His people, may the LORD his God be with him, and let him go up.'"

3. Isaiah 44:28 :
"who says of Cyrus, ‘He is My shepherd, and he will fulfill all that I desire,’ who says of Jerusalem, ‘She will be rebuilt,’ and of the temple, ‘Your foundation will be laid.’"

4. Isaiah 45:1-4 :
"This is what the LORD says to Cyrus His anointed, whose right hand I have grasped to subdue nations before him, to disarm kings, to open the doors before him so that the gates will not be shut: 'I will go before you and level the mountains; I will break down the gates of bronze and cut through the bars of iron. I will give you the treasures of darkness and the hidden riches of secret places, so that you may know that I am the LORD, the God of Israel, who calls you by name. For the sake of Jacob My servant and Israel My chosen one, I call you by name; I have given you a title of honor, though you have not known Me.'"

Historical Context:
Cyrus the Great conquered Babylon in 539 BC, and his decree is believed to have been issued shortly thereafter, around 538 BC. The decree allowed the Jewish exiles to return to their homeland and rebuild the Temple, which had been destroyed by Nebuchadnezzar II in 586 BC. This event is a pivotal moment in Jewish history, as it marks the end of the Babylonian captivity and the beginning of the Second Temple period.

Theological Significance:
Cyrus's Decree is often viewed as a divine intervention in history, where God uses a pagan king to accomplish His purposes. The decree is seen as a fulfillment of the prophecies of Isaiah and Jeremiah, demonstrating God's faithfulness to His covenant people. It underscores the belief that God is sovereign over all nations and rulers, orchestrating events to fulfill His divine plan.

Impact on Jewish Life and Worship:
The return to Jerusalem and the rebuilding of the Temple had profound implications for Jewish life and worship. It allowed the Jewish people to reestablish their religious practices and cultural identity centered around the Temple. The decree also set the stage for the later reforms of Ezra and Nehemiah, which further solidified Jewish religious and social structures.

Conclusion:
Cyrus's Decree remains a testament to God's providence and the fulfillment of His promises. It serves as a reminder of the ways in which God can use unexpected means to bring about His purposes and restore His people.
