Exodus 6:23-30 HNV

23 Aharon took Elisheva, the daughter of `Amminadav, the sister of Nachshon, as his wife; and she bore him Nadav and Avihu, El`azar and Itamar.
24 The sons of Korach: Assir, and Elkana, and Avi'asaf; these are the families of the Korchi.
25 El`azar Aharon's son took one of the daughters of Puti'el as his wife; and she bore him Pinechas. These are the heads of the fathers' houses of the Levites according to their families.
26 These are that Aharon and Moshe, to whom the LORD said, "Bring out the children of Yisra'el from the land of Mitzrayim according to their hosts."
27 These are those who spoke to Par`oh king of Mitzrayim, to bring out the children of Yisra'el from Mitzrayim. These are that Moshe and Aharon.
28 It happened on the day when the LORD spoke to Moshe in the land of Mitzrayim,
29 that the LORD spoke to Moshe, saying, "I am the LORD. Speak to Par`oh king of Mitzrayim all that I speak to you."
30 Moshe said before the LORD, "Behold, I am of uncircumcised lips, and how shall Par`oh listen to me?"
