1Yahweh said to Moses, “Now you shall see what I will do to Pharaoh, for by a strong hand he shall let them go, and by a strong hand he shall drive them out of his land.”
2God spoke to Moses, and said to him, “I am Yahweh. 3I appeared to Abraham, to Isaac, and to Jacob, as God Almighty; but by my name Yahweh I was not known to them. 4I have also established my covenant with them, to give them the land of Canaan, the land of their travels, in which they lived as aliens. 5Moreover I have heard the groaning of the children of Israel, whom the Egyptians keep in bondage, and I have remembered my covenant. 6Therefore tell the children of Israel, ‘I am Yahweh, and I will bring you out from under the burdens of the Egyptians, and I will rid you out of their bondage, and I will redeem you with an outstretched arm, and with great judgments. 7I will take you to myself for a people. I will be your God; and you shall know that I am Yahweh your God, who brings you out from under the burdens of the Egyptians. 8I will bring you into the land which I swore to give to Abraham, to Isaac, and to Jacob; and I will give it to you for a heritage: I am Yahweh.’”
9Moses spoke so to the children of Israel, but they didn’t listen to Moses for anguish of spirit, and for cruel bondage.
10Yahweh spoke to Moses, saying, 11“Go in, speak to Pharaoh king of Egypt, that he let the children of Israel go out of his land.”
12Moses spoke before Yahweh, saying, “Behold, the children of Israel haven’t listened to me. How then shall Pharaoh listen to me, when I have uncircumcised lips?” 13Yahweh spoke to Moses and to Aaron, and gave them a command to the children of Israel, and to Pharaoh king of Egypt, to bring the children of Israel out of the land of Egypt.
14These are the heads of their fathers’ houses. The sons of Reuben the firstborn of Israel: Hanoch, and Pallu, Hezron, and Carmi; these are the families of Reuben. 15The sons of Simeon: Jemuel, and Jamin, and Ohad, and Jachin, and Zohar, and Shaul the son of a Canaanite woman; these are the families of Simeon. 16These 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 one hundred thirty-seven years. 17The sons of Gershon: Libni and Shimei, according to their families. 18The sons of Kohath: Amram, and Izhar, and Hebron, and Uzziel; and the years of the life of Kohath were one hundred thirty-three years. 19The sons of Merari: Mahli and Mushi. These are the families of the Levites according to their generations. 20Amram took Jochebed his father’s sister to himself as wife; and she bore him Aaron and Moses. The years of the life of Amram were one hundred thirty-seven years. 21The sons of Izhar: Korah, and Nepheg, and Zichri. 22The sons of Uzziel: Mishael, Elzaphan, and Sithri. 23Aaron took Elisheba, the daughter of Amminadab, the sister of Nahshon, as his wife; and she bore him Nadab and Abihu, Eleazar and Ithamar. 24The sons of Korah: Assir, Elkanah, and Abiasaph; these are the families of the Korahites. 25Eleazar Aaron’s son took one of the daughters of Putiel as his wife; and she bore him Phinehas. These are the heads of the fathers’ houses of the Levites according to their families. 26These are that Aaron and Moses to whom Yahweh said, “Bring out the children of Israel from the land of Egypt according to their armies.” 27These are those who spoke to Pharaoh king of Egypt, to bring out the children of Israel from Egypt. These are that Moses and Aaron.
28On the day when Yahweh spoke to Moses in the land of Egypt, 29Yahweh said to Moses, “I am Yahweh. Tell Pharaoh king of Egypt all that I tell you.”
30Moses said before Yahweh, “Behold, I am of uncircumcised lips, and how shall Pharaoh listen to me?”
Jacob was the son of Isaac and Rebekah, born immediately after Esau, and Abraham was his grandfather. He achieved the right of the firstborn by trickery, in offering his older brother, Esau, food in exchange for the birthright, who cared little for this position. He also received the blessing of firstborn from his father Jacob before his death by cunning, and with the assistance of his mother Rebekah.
After his deception of Esau, receiving the blessing from his father, Jacob escaped to his uncle Laban, who in turn deceived Jacob into working for fourteen years for the marriage of Jacob to Leah, and then his beloved Rachel. Laban also sought to deceive Jacob of wages, but God intervened to ensure he would prosper. In a time of trial, when he feared the wrath of Esau, upon returning to the land of Canaan, Jacob had an encounter with God, and his name was changed to Israel, the one who wrestles with God. Even though his early life was characterized by deception, God worked through the situation to ensure that Jacob would be the one in the line of the patriarchs, to create a great nation and ultimately fulfill His purposes in the earth, especially through the future Messiah. The Messiah would guarantee the promise of the land to Abram and a person who would rule over Abraham's descendants, but also He would bring blessings to all the people of the earth (Gen 12:1-3).
In spite of Jacob's early failure by deception, God worked through him, and finally, Jacob became a different type of man after his struggle with God. As one has said,
"Despite Jacob’s faults, God chose him to be the leader of a great nation that still bears his name today. But for this, it is unlikely that we would know much about Jacob, who appears to be in the middle of events while the key players are those around him. There is no great wisdom or bravery in Jacob to speak of, and we are tempted to see him as little more than God’s passive instrument. If we are tempted to think that, because we aren’t in the spotlight performing great acts for God, we are unimportant to Him, then we should consider the life of Jacob and know that, in spite of our failings, God can and will still use us in His plan."
