Who am I that I should go to Pharaoh and free the Israelite's from Egypt
I will be with you. When you have freed the people of Israel bring them to this mountain where they will worship me
When I go to them and they ask me what is your name what should I say
You shall say to them יהיה sent you
I will fulfill your promise God
Thus Hashem Continue to tell Moshe what he is going to do: He said you will tell bnei Israel and The elders of Israel them that the God of your fathers has spoken to you and he will stretch out his hand and smite Egypt with plaques and after that I will let you go. I will bring you to the land of Israel but you will not be empty handed, you will take the gold and silvers of your neighbor take there cloths thus stripping Egypt of there goods.
