Acts 7:22-25

King James Version

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

²³ And when he was full 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, and smote the Egyptian:

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