Acts 7:22-25

So Moses was fully trained in the royal courts and educated in the highest wisdom Egypt had to offer, until he arose as a powerful prince and an eloquent orator. “When Moses turned forty, his heart was stirred for his people, the Israelites. One day he saw one of our people being violently mistreated, so he came to his rescue, and with his own hands Moses murdered the abusive Egyptian. Moses hoped that when the people realized how he had rescued one of their own, they would recognize him as their deliverer. How wrong he was!
