Acts 7:24-28

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?

Wilt thou kill me, as thou diddest the Egyptian yesterday?
