Moses
Exodus 32:11ESV·traditional attribution

But Moses implored the LORD his God and said, “O LORD, why does your wrath burn hot against your people, whom you have brought out of the land of Egypt with great power and with a mighty hand?

11. And Moses besought the Lord his God It is clear that this prayer sprang from faith, though in it he seems to fight against the very word of God; for God had said, Get thee down to thy people; but his answer is, Nay, it is thine.

Matthew Henry Presbyterian @wholebiblehenry

Here, I. God acquaints Moses with what was doing in the camp while he was absent, Exo 32:7, Exo 32:8. He could have told him sooner, as soon as the first step was taken towards it, and have hastened him down to prevent it; but he suffered it to come to this height, for wise and holy ends, and then sent him down to punish it.

And Moses besought the Lord his God,.... As the Lord was the God of Moses, his covenant God, and he had an interest in him, he made use of it in favour of the people of Israel: and said, why doth thy wrath wax hot against thy people?
