Acts 7:23-30

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? 28Wouldest thou kill me, as thou killedst the Egyptian yesterday? 29And Moses fled at this saying, and became a sojourner in the land of Midian, where he begat two sons. 30And when forty years were fulfilled, an angel appeared to him in the wilderness of mount Sinai, in a flame of fire in a bush.
