Acts 7:22-27

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

²³But when he was well-nigh 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, smiting the Egyptian:

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

²⁶And the day following he appeared unto them as they strove, and would have set them at one again, saying, Sirs, ye are brethren; why do ye wrong one to another?

²⁷But he that did his neighbor wrong thrust him away, saying, Who made thee a ruler and a judge over us?
