Moses prayed to the Lord his God, and said; Moses addressed this prayer to the Lord his God, and declared: "Why, O Lord, is your anger enkindled against your people? Let the wrath your mind has conceived cease. Remember Abraham, Issac, and Jacob, to whom you swore to give a land flowing with milk and honey." And the Lord was dissuaded from accomplishing the evil which he had threatened to inflict upon his people.
Exodus 32: 11, 15, 13, 14
Moses consecrated an altar to the Lord, and presented thereupon burnt offerings and sacrificial victims; he made an evening sacrifice as a fragrant offering to the Lord, in the presence of the sons of Israel.
