Acts 7:17-25

But as the time of the promise drew nigh which God vouchsafed unto Abraham, the people grew and multiplied in Egypt, till there arose another king over Egypt, who knew not Joseph. The same dealt craftily with our race, and ill-treated our fathers, that they should cast out their babes to the end they might not live. At which season Moses was born, and was exceeding fair; and he was nourished three months in his father’s house: and when he was cast out, Pharaoh’s daughter took him up, and nourished him for her own son. And Moses was instructed in all the wisdom of the Egyptians; and he was mighty in his words and works. But when he was well-nigh forty years old, it came into his heart to visit his brethren the children of Israel. And seeing one of them suffer wrong, he defended him, and avenged him that was oppressed, smiting the Egyptian: and he supposed that his brethren understood that God by his hand was giving them deliverance; but they understood not.
