Exodus 3:13-14  Then Moses said to God, ‘I am to go, then, to the sons of Israel and say to them, “The God of your father has sent me to you”. But if they ask me what his name is, what am I to tell them?’ And God said to Moses, ‘I Am who I Am. This,’ he added, ‘is what you must say to the sons of Israel: “I Am has sent me to you”.’

A podcast of these talks will be available shortly
