Acts 7:23-34

23 Now when he was forty years old, it came into his heart to visit his brethren, the children of Israel. 24 And seeing one of them suffer wrong, he defended and avenged him who was oppressed, and struck down the Egyptian. 25 For he supposed that his brethren would have understood that God would deliver them by his hand, but they did not understand. 26 And the next day he appeared to two of them as they were fighting, and tried to reconcile them, saying, 'Men, you are brethren; why do you wrong one another?' 27 But he who did his neighbor wrong pushed him away, saying, 'Who made you a ruler and a judge over us? 28 Do you want to kill me as you did the Egyptian yesterday?' 29 Then, at this saying, Moses fled and became a dweller in the land of Midian, where he had two sons.

30 And when forty years had passed, an Angel of the Lord appeared to him in a flame of fire in a bush, in the wilderness of Mount Sinai. 31 When Moses saw it, he marveled at the sight; and as he drew near to observe, the voice of the Lord came to him, 32 saying, 'I am the God of your fathers--the God of Abraham, the God of Isaac, and the God of Jacob.' And Moses trembled and dared not look. 33 'Then the Lord said to him, "Take your sandals off your feet, for the place where you stand is holy ground. 34 I have surely seen the oppression of my people who are in Egypt; I have heard their groaning and have come down to deliver them. And now come, I will send you to Egypt." '
