God said to Moses, “I AM WHO I AM”; and He said, “Thus you shall say to the sons of Israel, ‘I AM has sent me to you.’ ” 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.

It is I who have declared and saved and proclaimed, And there was no strange god among you; So you are My witnesses,” declares the Lord, “And I am God. Even from eternity I am He, And there is none who can deliver out of My hand; I act and who can reverse it?”
