John Calvin on Acts 7:34

34. In seeing I have seen. God promiseth now that he will deliver his people, that he may appoint Moses to be his minister afresh, because the former objection was taken away by so long space of time. For God is said to see our miseries when he hath respect to us, and is careful for our safety; as he is said again to shut his eyes, and turn his back, when as he seemeth to set light by our cause. In like sort is he said to come down. He needeth not to move out of his place to help us, for his hand reacheth throughout the heaven and earth; but this is referred unto our understanding. For, seeing that he did not deliver his people from their affliction, he might seem that he was afar off, and was busied about some other thing in heaven. Now he saith that the Israelites shall perceive that he is nigh unto them. The sum tendeth to this end, that Moses knowing the will of God, may not doubt to follow him as a guide, and the more boldly to employ himself about the delivery of the people, which he knew was the work of God. For we must note that he saith that he heard the mourning of the people. For although he hath respect unto those which are in misery and unjustly oppressed, yet when we lay our mournings and complaints in his lap, he is especially moved to have mercy; although this word may be taken for those blind and confused complaints which are not directed unto God, as it is taken oftentimes elsewhere.

Acts 7:35-37

35. This Moses, whom they had denied, saying, Who made thee a ruler and judge? him, I say, hath God sent to be a ruler and a redeemer, in the hand of the angel which appeared unto him in the bush. 36. He brought them out, having showed wonders and signs in the land of Egypt, and in the Red Sea, and in the wilderness forty years. 37. This is Moses, which said unto the children of Israel, The Lord your God shall raise up unto you a Prophet, out of the midst of your brethren, like unto me; hear him.
