Acts 7:23 ASV

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

²²  And Moses was instructed in all the wisdom of the Egyptians; and he was mighty in his words and works.

²³  But when he was well-nigh forty years old, it came into his heart to visit his brethren the children of Israel.

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

²⁵  and he supposed that his brethren understood that God by his hand was giving them deliverance; but they understood not.
