Who is there among you of all his people? His God be with him, and let him go up to Jerusalem, which is in Judah, and build the house of the LORD, God of Israel, (he is the God,) which is in Jerusalem. Ezra 1:3 NKJV
Let’s look at the context of this verse. After Israel had three waves of their people exiled to Babylon, Nebuchadnezzar, the King of Persia held the Jews in captivity for seventy years. In the first two verses of Ezra chapter one, God gave the King of Persia, Cyrus, who followed Nebuchadnezzar, a sense of urgency to put out a proclamation in writing to go to Jerusalem to rebuild the temple.
Cyrus was an ancient, cruel and pagan king. It’s interesting to me that this mighty king would proclaim the Jewish God, THE God and then give the Jews the green light to return to Jerusalem and build the temple to their God. This king ultimately allowed the exiled people to return to their homeland.
Based on Daniel, Ezra and many other major and minor prophets of the Bible, I believe God puts men and kingdoms in place to bring about His plan. Ezra chapter one verses one and two, tells us this. I believe it has been this way since the beginning of time.
