Exodus 3:13-14 Moses said to God, “Suppose I go to the Israelites and say to them, ‘The God of your fathers has sent me to you,’ and they ask me, ‘What is his name?’ Then what shall I tell them?” God said to Moses, “I AM WHO I AM. This is what you are to say to the Israelites: ‘I AM has sent me to you.'
I AM WHO I AM Hebrew is HAYAH ASHER HAYAH or ehyeh ašer ehyeh
I AM is HAYAH or ehyeh
How comes His name become YAHWEH or JEHOVAH?
