Exodus 6:24-30

6:24 And the sons of Korah; Assir, and Elkanah, and Abiasaph: these [are] the families of the Korhites. 6:25 And Eleazar Aaron’s son took him [one] of the daughters of Putiel to wife; and she bare him Phinehas: these [are] the heads of the fathers of the Levites according to their families. 6:26 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. 6:27 These [are] they which spake to Pharaoh king of Egypt, to bring out the children of Israel from Egypt: these [are] that Moses and Aaron. 6:28 And it came to pass on the day [when] the LORD spake unto Moses in the land of Egypt, 6:29 That the LORD spake unto Moses, saying, I [am] the LORD: speak thou unto Pharaoh king of Egypt all that I say unto thee. 6:30 And Moses said before the LORD, Behold, I [am] of uncircumcised lips, and how shall Pharaoh hearken unto me?
