1 Now these were the people of the province who came up out of the captivity of those exiles whom Nebuchadnezzar the king of Babylon had carried captive to Babylonia. They returned to Jerusalem and Judah, each to his own town. 2 They came with Zerubbabel, Jeshua, Nehemiah, Seraiah, Reelaiah, Mordecai,
Bilshan, Mispar, Bigvai, Rehum, and Baanah.
Ezra 2:1-2

1. Leave captivity

13 Brothers, I do not consider that I have made it my own. But one thing I do: forgetting what lies behind and straining forward to what lies ahead, 14 I press on toward the goal for the prize of the upward call of God in Christ Jesus.
Philippians 3:13-14

2 Thus says Cyrus king of Persia: The Lord, the God of heaven, has given me all the kingdoms of the earth, and he has charged me to build him a house at Jerusalem, which is in Judah. 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.
Ezra 1:2-3
