Verse 22. "Turned the heart of the king of Assyria" - I am of Calmet's mind, that king of Assyria is here put for king of Persia. Cyrus and his successors possessed all the rights and estates of the ancient kings of Assyria, and therefore the same monarch may be styled king of Assyria as well as king of Persia.
DARIUS had a very high character, as a wise, just, and merciful prince. To strengthen his title to the crown, he married two of the daughters of Cyrus, and, no doubt, to show his affection to this family, he the more cheerfully confirmed the edict which Cyrus had made in favour of the Jews.
