Thus saith Cyrus king of Persia, The LORD God of heaven hath given me {d} all the kingdoms of the earth; and he hath charged me to build him an house at Jerusalem, which is in Judah.

(d) For he was chief monarch and had many nations under his dominion, which this heathen king confesses to have received from the living God.

Wesley's Notes

1:2 All, and c. - In those parts of the world; all that vast empire formerly under the Assyrians and Babylonians. The gift of which he ascribes to the great God; by that express prophecy of Isaiah concerning him, Isa 44:28 45:1,13, so long before he was born; which prophecy the Jews had doubtlessly shewed him, which also carried a great evidence with it, especially to him who was so highly encouraged by it: or by a special illumination which God vouchsafed to him, as he did to Nebuchadnezzar and Darius, and some other Heathen princes.

Jamieson-Fausset-Brown Bible Commentary

2. 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 Da 4:1), it was literally true that the Persian empire was the greatest ruling power in the world at that time.

he hath charged me to build him an house at Jerusalem-The phraseology of this proclamation, independently of the express testimony of Josephus, affords indisputable evidence that Cyrus had seen (probably through means of Daniel, his venerable prime minister and favorite) those prophecies in which, two hundred years before he was born, his name, his victorious career, and the important services he should render to the Jews were distinctly foretold (Isa 44:28; 46:1-4). The existence of predictions so remarkable led him to acknowledge that all his kingdoms were gifts bestowed on him by "the Lord God of heaven," and prompted him to fulfil the duty which had been laid upon him long before his birth. This was the source and origin of the great favor he showed to the Jews. The proclamation, though issued "in the first year of Cyrus" [Ezr 1:1], did not take effect till the year following.

Matthew Henry's Concise Commentary

1:1-4 The Lord stirred up the spirit of Cyrus. The hearts of kings are in the hand of the Lord. God governs the world by his influence on the spirits of men; whatever good they do, God stirs up their spirits to do it. It was during the captivity of the Jews, that God principally employed them as the means of calling the attention of the heathen to him. Cyrus took it for granted, that those among the Jews who were able, would offer free-will offerings for the house of God. He would also have them supplied out of his kingdom. Well-wishers to the temple should be well-doers for it.
