New American Standard Bible (NASB)
Exodus 6
25 Aaron’s son Eleazar married one of the daughters of Putiel, and she bore him Phinehas. These are the heads of the fathers’ households of the Levites according to their families.
26 It was the same Aaron and Moses to whom the Lord said, "Bring out the sons of Israel from the land of Egypt according to their hosts."
27 They were the ones who spoke to Pharaoh king of Egypt about bringing out the sons of Israel from Egypt; it was the same Moses and Aaron.
28 Now it came about on the day when the Lord spoke to Moses in the land of Egypt,
29 that the Lord spoke to Moses, saying, "I am the Lord; speak to Pharaoh king of Egypt all that I speak to you."
30 But Moses said before the Lord, "Behold, I am unskilled in speech; how then will Pharaoh listen to me?"
Exodus 7
1 Then the Lord said to Moses, "See, I make you as God to Pharaoh, and your brother Aaron shall be your prophet.
2 You shall speak all that I command you, and your brother Aaron shall speak to Pharaoh that he let the sons of Israel go out of his land.
3 But I will harden Pharaoh’s heart that I may multiply My signs and My wonders in the land of Egypt.
4 When Pharaoh does not listen to you, then I will lay My hand on Egypt and bring out My hosts, My people the sons of Israel, from the land of Egypt by great judgments.
5 The Egyptians shall know that I am the Lord, when I stretch out My hand on Egypt and bring out the sons of Israel from their midst."
