6 He said also, "I am the God of your father, the God of Abraham, the God of Isaac, and the God of Jacob." Then Moses hid his face, for he was afraid to look at God.

15 God, furthermore, said to Moses, "Thus you shall say to the sons of Israel, 'The LORD , the God of your fathers, the God of Abraham, the God of Isaac, and the God of Jacob, has sent me to you.' This is My name forever, and this is My memorial-name to all generations.
