2. He shall replenish his coffers very much (v. 3): I will give thee the treasures of darkness, treasures of gold and silver, that have been long kept close under lock and key and had not seen the light of many years, or had been buried under ground by the inhabitants, in their fright, upon the taking of the city. The riches of many nations had been brought to Babylon, and Cyrus seized all together. The hidden riches of secret places, which belonged either to the crown or to private persons, shall all be a prey to Cyrus. Thus God, designing him to do a piece of service to his church, paid him richly for it beforehand; and Cyrus very honestly owned God's goodness to him, and, in consideration of that, released the captives. Ezra i. 2, God has given me all the kingdoms of the earth and thereby has obliged me to build him a house at Jerusalem.
