Thematic Bible: Moses interceded for those who worshipped

On the next day Moses said to the people, "You yourselves have committed a great sin; and now I am going up to the LORD, perhaps I can make atonement for your sin."

"Why should the Egyptians speak, saying, 'With evil intent He brought them out to kill them in the mountains and to destroy them from the face of the earth'? Turn from Your burning anger and change Your mind about doing harm to Your people. "Remember Abraham, Isaac, and Israel, Your servants to whom You swore by Yourself, and said to them, 'I will multiply your descendants as the stars of the heavens, and all this land of which I have spoken I will give to your descendants, and they shall inherit it forever.'" read more.

"I fell down before the LORD, as at the first, forty days and nights; I neither ate bread nor drank water, because of all your sin which you had committed in doing what was evil in the sight of the LORD to provoke Him to anger. "For I was afraid of the anger and hot displeasure with which the LORD was wrathful against you in order to destroy you, but the LORD listened to me that time also. "The LORD was angry enough with Aaron to destroy him; so I also prayed for Aaron at the same time.
