Moses is one of the towering figures of the Old Testament. He was called by God to lead the Hebrew people from slavery to Egypt and later led them to wonder in the wilderness for forty years. Moses received the Ten Commandments while the people camped at Mt. Sinai and represented the Lord (Yahweh) to the people and the people to God as they were constituted as a nation at Sinai. These activities are related to this great Old Testament character.
