27 And who spoke to [the] Pharaoh king of Egypt about bringing the Israelites out of Egypt; these are that Moses and Aaron.
28 On the day when the Lord spoke to Moses in Egypt,
29 The Lord said to Moses, I am the Lord; tell Pharaoh king of Egypt all that I say to you.
30 But Moses said to the Lord, Behold, I am of deficient and impeded speech; how then shall Pharaoh listen to me?
