Thematic Bible: His controversy with his wife on account of circumcision

And Moses took his wife and his sons and put them on an ass and went back to the land of Egypt: and he took the rod of God in his hand. And the Lord said to Moses, When you go back to Egypt, see that you do before Pharaoh all the wonders which I have given you power to do: but I will make his heart hard and he will not let the people go. And you are to say to Pharaoh, The Lord says, Israel is the first of my sons: read more.
And I said to you, Let my son go, so that he may give me worship; and you did not let him go: so now I will put the first of your sons to death. Now on the journey, at the night's resting-place, the Lord came in his way and would have put him to death. Then Zipporah took a sharp stone, and cutting off the skin of her son's private parts, and touching his feet with it, she said, Truly you are a husband of blood to me. So he let him go. Then she said, You are a husband of blood because of the circumcision.
