Forty years prior to the end of the four hundred years, Moses decided against the court life of Pharaoh of Egypt and threw in his lot with his Israelite brothers and offered himself to them as their leader to lead them out of slavery. “He was supposing his brothers would grasp that God was giving them salvation by his hand, but they did not grasp it.” God had then not sent Moses to deliver the enslaved people.

Acts 7:23-29.
