Acts 7:21

17But when the time of the promise drew nigh, which God had sworn to Abraham, the people grew and multiplied in Egypt,

18Till another king arose, which knew not Joseph.

19The 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.

20In which time Moses was born, and was exceeding fair, and nourished up in his father’s house three months:

21And when he was cast out, Pharaoh’s daughter took him up, and nourished him for her own son.

22And Moses was learned in all the wisdom of the Egyptians, and was mighty in words and in deeds.

23And when he was full forty years old, it came into his heart to visit his brethren the children of Israel.

24And seeing one of them suffer wrong, he defended him, and avenged him that was oppressed, and smote the Egyptian:

25For he supposed his brethren would have understood how that God by his hand would deliver them: but they understood not.
