Ezra 1:2BSB·traditional attribution

“This is what Cyrus king of Persia says: ‘The LORD, the God of heaven, who has given me all the kingdoms of the earth, has appointed me to build a house for Him at Jerusalem in Judah.

Matthew Henry Presbyterian @wholebiblehenry

It will be proper for us here to consider, 1. What was the state of the captive Jews in Babylon. It was upon many accounts very deplorable; they were under the power of those that hated them, had nothing they could call their own; they had no temple, no altar; if they sang psalms, their enemies ridiculed them; and yet they had prophets among them.

Commenting on Ezra 1:1-4

John Gill Reformed Baptist @doctorgill

Thus saith Cyrus king of Persia,.... Of whom, and this edict of his, Isaiah prophesied two hundred years before he was born, Isa 44:28 the Lord God of heaven hath given me all the kingdoms of the earth; many he had conquered before he took Babylon, and then the whole Babylonian monarchy fell into his hands.

Jamieson-Fausset-Brown Reformed @jfbcommentary

The Lord God of heaven hath given me all the kingdoms of the earth--Though this is in the Oriental style of hyperbole (see also Dan 4:1), it was literally true that the Persian empire was the greatest ruling power in the world at that time.
