Isaiah 45:3-4

3, 4. Treasures of darkness Perhaps “darkness” is to offset “riches of secret places” in the parallel member. These treasures were to be taken by Cyrus, or given to him in his various conquests. The amount received from Croesus in Lydia alone was said to be one hundred millions sterling. Added to these were all the resources of Babylon, the “exactress of gold.” Cyrus was to learn from such prosperity, first, that the Lord fulfilled his promise to the letter; and second, that he was the true God, the God of Israel. He had called Cyrus by name as Israel’s redeemer. By this and other facts, Cyrus could not but believe and accept the prophecy as really intended for himself.
