Moses Moses was the founding leader of Israel as a nation. God used Moses at a critical juncture in the history of his people. He was the prophet who received the law and mediated God’s covenant with Israel at Mount Sinai (Exod 19:3-6). He was also the first known writer of Scripture. The younger brother of Miriam and Aaron, Moses was born in Egypt under dangerous circumstances (Exod 1:15–2:2). The Egyptian pharaoh, fearing a rebellion, had decreed that all Hebrew boys be killed at birth.

The covenant at Sinai was designed to teach the Israelites about God’s nature and character as they lived out his Torah, his instructions. The covenant used a familiar political form, the suzerain-vassal treaty, in which a great king (the suzerain) made a treaty with a nation he had subjected as a vassal people. In such a treaty, the conquered people would declare their absolute loyalty to the king and obedience to his demands.
