Exodus 3:2-4 New King James Version (NKJV)
2 And the Angel of the Lord appeared to him in a flame of fire from the midst of a bush. So he looked, and behold, the bush was burning with fire, but the bush was not consumed. 3 Then Moses said, “I will now turn aside and see this great sight, why the bush does not burn.”
4 So when the Lord saw that he turned aside to look, God called to him from the midst of the bush and said, “Moses, Moses!”
And he said, “Here I am.”
Exodus 3:2-4 New International Version (NIV)
2 There the angel of the Lord appeared to him in flames of fire from within a bush. Moses saw that though the bush was on fire it did not burn up. 3 So Moses thought, “I will go over and see this strange sight—why the bush does not burn up.”
4 When the Lord saw that he had gone over to look, God called to him from within the bush, “Moses! Moses!”
And Moses said, “Here I am.”
Acts 7:30-35 New King James Version (NKJV)
30 “And when forty years had passed, an Angel [a]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.” ’
35 “This Moses whom they rejected, saying, ‘Who made you a ruler and a judge?’ is the one God sent to be a ruler and a deliverer by the hand of the Angel who appeared to him in the bush.
Acts 7:30-35 New International Version (NIV)
30 “After forty years had passed, an angel appeared to Moses in the flames of a burning bush in the desert near Mount Sinai. 31 When he saw this, he was amazed at the sight. As he went over to get a closer look, he heard the Lord say: 32 ‘I am the God of your fathers, the God of Abraham, Isaac and Jacob.’[a] Moses trembled with fear and did not dare to look.
33 “Then the Lord said to him, ‘Take off your sandals, for the place where you are standing is holy ground. 34 I have indeed seen the oppression of my people in Egypt. I have heard their groaning and have come down to set them free. Now come, I will send you back to Egypt.’[b]
35 “This is the same Moses they had rejected with the words, ‘Who made you ruler and judge?’ He was sent to be their ruler and deliverer by God himself, through the angel who appeared to him in the bush.
