13 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?”
14 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.’”
This most revered name of God contains wonder and mystery. It speaks of His eternal nature, but it also contains impenetrable depths, beyond anyone’s ability to explain. One thing it does tell the Israelites, though (and ourselves, by extension) is that God is enough. He is always more than enough. The pre-existent eternal One is all-sufficient. He is ‘a living and constant presence.’ Tom Hale: ‘Applied OT Commentary, p.212
‘What Moses asked was, “What does Your name mean? What kind of a God are you?” God explained that the name Jehovah is a dynamic name, based on the Hebrew verb “to be” or “to become.” He is the self-existent One who always was, always is, and always will be, the faithful and dependable God who calls Himself “I AM.” Centuries later, Jesus would take the name “I AM” and complete it: “I am the bread of life” (John 6:35), “I am the light of the world” (8:12), “I am the true vine” (15:1), and so on.’ Warren W. Wiersbe: ‘OT Commentary,’ pp.150, 151.
