Acts 7:20-23

It was at this [critical] time that Moses was born; and he was lovely in the sight of God, and for three months he was nourished in his father’s house. [Ex 2:2] Then when he was set outside [to die], Pharaoh’s daughter rescued him and claimed him for herself, and cared for him as her own son. [Ex 2:5, 6, 10] So Moses was educated in all the wisdom and culture of the Egyptians, and he was a man of power in words and deeds. But when he reached the age of forty, it came into his heart to visit his brothers, the sons of Israel.
