Exodus.
Chapter 6.
Then the Lord said to Moses, “Now you will see what I will do to Pharaoh, for compelled by my strong hand he will release them, and by my strong hand he will drive them out of his land.” 
God spoke to Moses and said to him, “I am the Lord. 
I appeared to Abraham, to Isaac, and to Jacob as God Almighty, but by my name ‘the Lord’ I was not known to them. 
I also established my covenant with them to give them the land of Canaan, where they were living as resident foreigners. 
I have also heard the groaning of the Israelites, whom the Egyptians are enslaving, and I have remembered my covenant. 
Therefore, tell the Israelites, ‘I am the Lord. I will bring you out from your enslavement to the Egyptians, I will rescue you from the hard labor they impose, and I will redeem you with an outstretched arm and with great judgments. 
I will take you to myself for a people, and I will be your God. Then you will know that I am the Lord your God, who brought you out from your enslavement to the Egyptians. 
I will bring you to the land I swore to give to Abraham, to Isaac, and to Jacob – and I will give it to you as a possession. I am the Lord!’” 
Moses told this to the Israelites, but they did not listen to him because of their discouragement and hard labor. 
Then the Lord said to Moses, 
“Go, tell Pharaoh king of Egypt that he must release the Israelites from his land.” 
But Moses replied to the Lord, “If the Israelites did not listen to me, then how will Pharaoh listen to me, since I speak with difficulty?” 
The Lord spoke to Moses and Aaron and gave them a charge for the Israelites and Pharaoh king of Egypt to bring the Israelites out of the land of Egypt. 
These are the heads of their fathers’ households: The sons of Reuben, the firstborn son of Israel, were Hanoch and Pallu, Hezron and Carmi. These were the clans of Reuben. 
The sons of Simeon were Jemuel, Jamin, Ohad, Jakin, Zohar, and Shaul, the son of a Canaanite woman. These were the clans of Simeon. 
Now these are the names of the sons of Levi, according to their records: Gershon, Kohath, and Merari. (The length of Levi’s life was 137 years.) 
The sons of Gershon, by their families, were Libni and Shimei. 
The sons of Kohath were Amram, Izhar, Hebron, and Uzziel. (The length of Kohath’s life was 133 years.) 
The sons of Merari were Mahli and Mushi. These were the clans of Levi, according to their records. 
Amram married his father’s sister Jochebed, and she bore him Aaron and Moses. (The length of Amram’s life was 137 years.) 
The sons of Izhar were Korah, Nepheg, and Zikri. 
The sons of Uzziel were Mishael, Elzaphan, and Sithri. 
Aaron married Elisheba, the daughter of Amminadab and sister of Nahshon, and she bore him Nadab and Abihu, Eleazar and Ithamar. 
The sons of Korah were Assir, Elkanah, and Abiasaph. These were the Korahite clans. 
Now Eleazar son of Aaron married one of the daughters of Putiel and she bore him Phinehas. These are the heads of the fathers’ households of Levi according to their clans. 
It was the same Aaron and Moses to whom the Lord said, “Bring the Israelites out of the land of Egypt by their regiments.” 
They were the men who were speaking to Pharaoh king of Egypt, in order to bring the Israelites out of Egypt. It was the same Moses and Aaron. 
When the Lord spoke to Moses in the land of Egypt, 
he said to him, “I am the Lord. Tell Pharaoh king of Egypt all that I am telling you.” 
But Moses said before the Lord, “Since I speak with difficulty, why should Pharaoh listen to me?”
