Through the edict of Cyrus, God made it possible for the people of Judah to return to Jerusalem. He ensured that they have the freedom to go back. He ensured that they have all the resources needed for them to go back. He also made sure that they had the authority to rebuild the temple and the resources needed to do so.
3 Whoever is among you of all his people, may his God be with him, and let him go up to Jerusalem, which is in Judah, and rebuild the house of the LORD, the God of Israel he is the God who is in Jerusalem.
