Acts 7:17-29

But when the time of the promise drew nigh, which God had sworn to Abraham, the people grew and multiplied in Egypt, Till another king arose, which knew not Joseph. The same dealt subtilly with our kindred, and evil entreated our fathers, so that they cast out their young children, to the end they might not live. In which time Moses was born, and was exceeding fair, and nourished up in his father's house three months: and when he was cast out, Pharaoh's daughter took him up, and nourished him for her own son. And Moses was learned in all the wisdom of the Egyptians, and was mighty in words and in deeds. And when he was full 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, and smote the Egyptian: for he supposed his brethren would have understood how that God by his hand would deliver them: but they understood not. And the next day he shewed himself unto them as they strove, and would have set them at one again, saying, Sirs, ye are brethren; why do ye wrong one to another? But he that did his neighbour wrong thrust him away, saying, Who made thee a ruler and a judge over us? Wilt thou kill me, as thou diddest the Egyptian yesterday? Then fled Moses at this saying, and was a stranger in the land of Madian, where he begat two sons.
