Exodus 3:13-14 are two of the most familiar verses in the Old Testament: “Then Moses said to God, “If I come to the people of Israel and say to them, ‘The God of your fathers has sent me to you,’ and they ask me, ‘What is his name?’ what shall I say to them?” God said to Moses, “I am who I am.” And he said, “Say this to the people of Israel: ‘I am has sent me to you.’ ” God reveals his name here in the first person (ehyeh – I AM), but most of the time the Old Testament has the divine name in the third person (Yahweh). Biblical names typically have meanings, so what is the meaning of this name for God?
People can go up to my website for a detailed discussion of this. I favor the second view: “I am he who causes to be all that is,” arguing for a hiphil, a causative, vocalization of the verbal name phrase.
Also a youtube video I created.
