Moses ascends Mount Sinai for a second time and Yahweh passes before him and says: 'Yahweh, Yahweh, a god of compassion, and showing favor, slow to anger, and great in kindness and in truth, who shows kindness to the thousandth generation, forgiving wrongdoing and injustice and wickedness, but will by no means clear the guilty, causing the consequences of the parent's wrongdoing to befall their children, and their children's children, to the third and fourth generation' Moses then fasts for another forty days while Yahweh carves the Ten Commandments into the second set of stone tablets. After the tablets are completed, light emanates from the face of Moses for the rest of his life, causing him to wear a veil so he does not frighten people.
