 If Abraham trusts God that he has this great blessing for him, then he's going to get up and pack his things and he's going to leave Ur of the Chaldees where he was living and raised. If Moses and the children of Israel trust God, then when he says, choose a lamb one year old without spot or blemish and sacrifice it and eat it within your house and get ready because you're going to leave Egypt, then they will do it.
