Acts 7:22-24

Amplified Bible

²² So Moses was educated in all the wisdom and culture of the Egyptians, and he was a man of power in words and deeds. ²³ But when he reached the age of forty, it came into his heart to visit his brothers, the sons of Israel. ²⁴ And when he saw one [of them] being treated unfairly, he defended the oppressed man and avenged him by striking and killing the Egyptian.
