Acts 7:24-27

And seeing one of them suffer wrong, he defended him, and avenged him that was oppressed, and smote the Egyptian: for he supposed his brethren would have understood how that God by his hand would deliver them: but they understood not. And the next day he shewed himself 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? But he that did his neighbour wrong thrust him away, saying, Who made thee a ruler and a judge over us?
