Deuteronomy 9:18 CEV

[18] I bowed down at the place of worship and prayed to the LORD, without eating or drinking for forty days and nights. You had committed a terrible sin by making that idol, and the LORD hated what you had done. He was angry enough to destroy all of you and Aaron as well. So I prayed for you and Aaron as I had done before, and this time the LORD answered my prayers.
