Moses: But they will not believe me, nor listen to my voice: for they will say, The Lord has not appeared to you.
The Lord: What is that in your hand?
Moses: A rod.
The Lord: Cast the rod on the ground.
Moses cast his rod on the ground, and it became a serpent; and Moses fled from it.
The Lord: Put out your hand and take the serpent by the tail.
Moses put forth his hand, and caught the serpent by the tail, and it became a rod in his hand.
The Lord: That they may believe that the Lord God of their fathers, the God of Abraham, the God of Isaac, and the God of Jacob, has appeared to you. Now put your hand into your bosom.
Moses put his hand into his bosom: and when he took it out his hand was leprous as snow.
The Lord: Put your hand into your bosom again.
Moses put his hand into his bosom again; and plucked it out of his bosom, and it was turned again as his other flesh.
The Lord: If they will not believe you, nor listen to the voice of the first sign, they will believe the voice of the latter sign. And if they will not believe also these two signs, nor listen to your voice, you shall take of the water of the river, and pour it on the dry land: and the water which you take out of the river shall become blood on the dry land.
Moses: My Lord, I am not eloquent, neither before, nor since you have spoken to your servant: but I am slow of speech, and of a slow tongue.
The Lord: Who has made man’s mouth? Who makes the dumb, or deaf, or the seeing, or the blind? Is it not I the Lord? Now therefore go, and I will be with your mouth, and teach you what you shall say.
Moses: My Lord, please send someone else. (ESV)
The anger of the Lord was kindled against Moses.
The Lord: Isn’t Aaron the Levite your brother? I know that he can speak well. And he comes forth to meet you: and when he sees you, he will be glad in his heart. And you shall speak to him, and put words in his mouth: and I will be with your mouth, and with his mouth, and will teach you what you shall do. And he shall be your spokesman to the people: and he shall be to you as a mouth, and you shall be to him as God. And you shall take this rod in your hand, wherewith you shall do signs.
Moses returned to Jethro his father-in-law.
Moses (to Jethro): Let me go and return to my brethren who are in Egypt, and see whether they are yet alive.
Jethro (to Moses): Go in peace.
The Lord (to Moses in Midian): Go, return into Egypt: for all the men are dead who sought your life.
And Moses took his wife and his sons, and set them on a donkey. And Moses returned to the land of Egypt with the rod of God in his hand.
The Lord: When you return into Egypt, see that you do all those wonders before Pharaoh, which I have put in your hand. But I will harden his heart, that he shall not let the people go. And you shall say to Pharaoh, the Lord said, Israel is my son, even my firstborn: And I say to you, Let my son go, that he may serve me: and if you refuse to let him go, I will slay your son, even your firstborn.
And on the way in the inn, the Lord met Moses and sought to kill him.
Then Zipporah took a sharp stone, and cut off the foreskin of her son, and cast it at Moses’ feet.
Zipporah: Surely a bloody husband you are to me.
She said this because of the circumcision.
So God let Moses go.
Pulpit Commentary says of this passage:
Moses was seized with a sudden and dangerous illness, which he rightly regarded, as a God-inflicted punishment, sent to chastise his sin of not circumcising his son. Zipporah understood the matter in the same way; and, as her husband was too ill to perform the rite, she herself with her own hand cut off her boy’s foreskin, and, still indignant at what she had been forced to do, cast it at her husband’s feet, with the reproach – “Surely a bloody husband you are to me.” Once the rite was performed, however reluctantly, God’s anger was appeased. He allowed Moses to recover his health and to pursue his journey
The Lord (to Aaron): Go into the wilderness to meet Moses.
And Aaron went, and met Moses in the mount of God, and kissed him.
And Moses told Aaron all the words of the Lord who had sent him, and all the signs which he had commanded him.
And Moses and Aaron went and gathered together all the elders of the children of Israel: And Aaron spake all the words which the Lord had spoken to Moses, and did the signs in the sight of the people. And the people believed: and when they heard that the Lord had visited the children of Israel, and that he had looked on their affliction, then they bowed their heads and worshipped.
