Exodus 4Q22 (paleo Exodm), Column 1
2 These are that Aaron and Moses to whom
3 the Lord said, Bring out the children of Israel from the land of Egypt according
4 to their armies. These are they which spake to Pharoah king of Egypt to bring out the children of Israel.
5 from Egypt: these are that Moses and Aaron. And it came to pass on the day when the Lord spake
6 unto Moses in the Land of Egypt,
7 That the Lord spake unto Moses, saying, I am the Lord: speak thou unto Pharoah king of Egypt
8 all that I say unto thee. And Moses said before the Lord,
9 Behold, I am of uncircumcised lips, and how shall Pharoah hearken unto me?
10 And the Lord said unto Moses, See, I have made thee a god to Pharoah: and Aaron thy brother shall be
11 thy prophet. Thou shalt speak all that I command thee: and Aaron thy brother shall speak unto
12 Pharoah, that he send the children of Israel out of his land. And I will harden Pharoah’s heart
13 and multiply my signs and my wonders in the land of Egypt.
