Thus saith Cyrus king of Persia, All the kingdoms of the earth hath the LORD God of heaven given me; and he hath charged me to build him an house in Jerusalem, which is in Judah. Who is there among you of all his people? The LORD his God be with him, and let him go up.
These last two verses of this book have a double aspect. 1. They look back to the prophecy of Jeremiah, and show how that was accomplished, Ch2 36:22. God had, by him, promised the restoring of the captives and the rebuilding of Jerusalem, at the end of seventy years; and that time to favour Sion, that set time, came at last.
Commenting on 2 Chronicles 36:22-23
Thus saith Cyrus king of Persia, All the kingdoms of the earth hath the LORD God of heaven given me; and he hath charged me to build him an house in Jerusalem, which [is] in Judah. Who [is there] among you of all his people? The LORD his God [be] with him, and let him go up.
