1Moses answered, “But, behold, they will not believe me, nor listen to my voice; for they will say, ‘Yahweh has not appeared to you.’”
2Yahweh said to him, “What is that in your hand?”
He said, “A rod.”
3He said, “Throw it on the ground.”
He threw it on the ground, and it became a snake; and Moses ran away from it.
4Yahweh said to Moses, “Stretch out your hand, and take it by the tail.”
He stretched out his hand, and took hold of it, and it became a rod in his hand.
5“This is so that they may believe that Yahweh, the God of their fathers, the God of Abraham, the God of Isaac, and the God of Jacob, has appeared to you.” 6Yahweh said furthermore to him, “Now put your hand inside your cloak.”
He put his hand inside his cloak, and when he took it out, behold, his hand was leprous, as white as snow.
7He said, “Put your hand inside your cloak again.”
He put his hand inside his cloak again, and when he took it out of his cloak, behold, it had turned again as his other flesh.
8“It will happen, if they will not believe you or listen to the voice of the first sign, that they will believe the voice of the latter sign. 9It will happen, if they will not believe even these two signs or listen to your voice, that you shall take of the water of the river, and pour it on the dry land. The water which you take out of the river will become blood on the dry land.”
10Moses said to Yahweh, “O Lord, I am not eloquent, neither before now, nor since you have spoken to your servant; for I am slow of speech, and of a slow tongue.”
11Yahweh said to him, “Who made man’s mouth? Or who makes one mute, or deaf, or seeing, or blind? Isn’t it I, Yahweh? 12Now therefore go, and I will be with your mouth, and teach you what you shall speak.”
13Moses said, “Oh, Lord, please send someone else.”
14Yahweh’s anger burned against Moses, and he said, “What about Aaron, your brother, the Levite? I know that he can speak well. Also, behold, he is coming out to meet you. When he sees you, he will be glad in his heart. 15You shall speak to him, and put the words in his mouth. I will be with your mouth, and with his mouth, and will teach you what you shall do. 16He will be your spokesman to the people. It will happen that he will be to you a mouth, and you will be to him as God. 17You shall take this rod in your hand, with which you shall do the signs.”
18Moses went and returned to Jethro his father-in-law, and said to him, “Please let me go and return to my brothers who are in Egypt, and see whether they are still alive.”
Jethro said to Moses, “Go in peace.”
19Yahweh said to Moses in Midian, “Go, return into Egypt; for all the men who sought your life are dead.”
20Moses took his wife and his sons, and set them on a donkey, and he returned to the land of Egypt. Moses took God’s rod in his hand. 21Yahweh said to Moses, “When you go back into Egypt, see that you do before Pharaoh all the wonders which I have put in your hand, but I will harden his heart and he will not let the people go. 22You shall tell Pharaoh, ‘Yahweh says, Israel is my son, my firstborn, 23and I have said to you, “Let my son go, that he may serve me;” and you have refused to let him go. Behold, I will kill your firstborn son.’”
24On the way at a lodging place, Yahweh met Moses and wanted to kill him. 25Then Zipporah took a flint, and cut off the foreskin of her son, and cast it at his feet; and she said, “Surely you are a bridegroom of blood to me.”
26So he let him alone. Then she said, “You are a bridegroom of blood,” because of the circumcision.
27Yahweh said to Aaron, “Go into the wilderness to meet Moses.”
He went, and met him on God’s mountain, and kissed him. 28Moses told Aaron all Yahweh’s words with which he had sent him, and all the signs with which he had instructed him. 29Moses and Aaron went and gathered together all the elders of the children of Israel. 30Aaron spoke all the words which Yahweh had spoken to Moses, and did the signs in the sight of the people. 31The people believed, and when they heard that Yahweh had visited the children of Israel, and that he had seen their affliction, then they bowed their heads and worshiped.
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."
