14 These are the heads of their fathers' houses: the sons of Reuben, the firstborn of Israel: Enoch and Phallu, Hezron and Carmi: these are the families of Reuben. 15 —And the sons of Simeon: Jemuel, and Jamin, and Ohad, and Jachin, and Zohar, and Saul the son of a Canaanitish woman: these are the families of Simeon. 16 And these are the names of the sons of Levi, according to their generations: Gershon, and Kohath, and Merari. And the years of the life of Levi were a hundred and thirty-seven years. 17 The sons of Gershon: Libni and Shimei, according to their families. 18 And the sons of Kohath: Amram, and Jizhar, and Hebron, and Uzziel. And the years of the life of Kohath were a hundred and thirty-three years. 19 And the sons of Merari: Mahli and Mushi: these are the families of Levi according to their generations. 20 And Amram took Jochebed his aunt as wife; and she bore him Aaron and Moses. And the years of the life of Amram were a hundred and thirty-seven years. 21 And the sons of Jizhar: Korah, and Nepheg, and Zicri. 22 And the sons of Uzziel: Mishael, and Elzaphan, and Sithri. 23 And Aaron took Elisheba, daughter of Amminadab, sister of Nahshon, as wife; and she bore him Nadab and Abihu, Eleazar and Ithamar. 24 And the sons of Korah: Assir, and Elkanah, and Abiasaph: these are the families of the Korahites. 25 And Eleazar Aaron's son took [one] of the daughters of Putiel as wife; and she bore him Phinehas: these are the heads of the fathers of the Levites according to their families. 26 This is that Aaron and Moses, to whom Jehovah said, Bring out the children of Israel from the land of Egypt according to their hosts. 27 These are they who spoke to Pharaoh king of Egypt, to bring out the children of Israel from Egypt: this is that Moses and Aaron. 28 And it came to pass on the day when Jehovah spoke to Moses in the land of Egypt, 29 that Jehovah spoke to Moses, saying, I am Jehovah: speak thou unto Pharaoh king of Egypt all that I say unto thee. 30 And Moses said before Jehovah, Behold, I am of uncircumcised lips, and how will Pharaoh hearken unto me?

Commentary on Exodus 6:14-30

(Read Exodus 6:14-30)

Moses and Aaron were Israelites; raised up unto them of their brethren, as Christ also should be, who was to be the Prophet and Priest, the Redeemer and Lawgiver of the people of Israel. Moses returns to his narrative, and repeats the charge God had given him to deliver his message to Pharaoh, and his objection against it. Those who have spoken unadvisedly with their lips ought to reflect upon it with regret, as Moses seems to do here."Uncircumcised," is used in Scripture to note the unsuitableness there may be in any thing to answer its proper purpose; as the carnal heart and depraved nature of fallen man are wholly unsuited to the services of God, and to the purposes of his glory. It is profitable to place no confidence in ourselves, all our sufficiency must be in the Lord. We never can trust ourselves too little, or our God too much. I can do nothing by myself, said the apostle, but I can do all things through Christ which strengtheneth me.
