26. These are that Aaron and Moses, to whom the LORD said, Bring out the children of Israel from the land of Egypt according to their armies.
27. These are they who spoke to Pharaoh, king of Egypt, to bring out the children of Israel from Egypt: these are that Moses and Aaron.
28. And it came to pass, 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 thou to Pharaoh, king of Egypt, all that I say to thee.
30. And Moses said before the LORD, Behold, I am of uncircumcised lips, and how shall Pharaoh hearken to me?
