Exodus 34:5–8 (NLT) — 5 Then the LORD came down in a cloud and stood there with him; and he called out his own name, Yahweh. 6 The LORD passed in front of Moses, calling out, “Yahweh! The LORD! The God of compassion and mercy! I am slow to anger and filled with unfailing love and faithfulness. 7 I lavish unfailing love to a thousand generations. I forgive iniquity, rebellion, and sin. But I do not excuse the guilty. I lay the sins of the parents upon their children and grandchildren; the entire family is affected— even children in the third and fourth generations.” 8 Moses immediately threw himself to the ground and worshiped.

Exodus 3:13–15 (NLT) — 13 But Moses protested, “If I go to the people of Israel and tell them, ‘The God of your ancestors has sent me to you,’ they will ask me, ‘What is his name?’ Then what should I tell them?” 14 God replied to Moses, “I AM WHO I AM. Say this to the people of Israel: I AM has sent me to you.” 15 God also said to Moses, “Say this to the people of Israel: Yahweh, the God of your ancestors—the God of Abraham, the God of Isaac, and the God of Jacob—has sent me to you. This is my eternal name, my name to remember for all generations.
