Exodus 4:21-26

New International Version

²¹ The Lord said to Moses, “When you return to Egypt, see that you perform before Pharaoh all the wonders^(A) I have given you the power to do. But I will harden his heart^(B) so that he will not let the people go.^{(C) 22} Then say to Pharaoh, ‘This is what the Lord says: Israel is my firstborn son,^{(D) 23} and I told you, “Let my son go,^(E) so he may worship^(F) me.” But you refused to let him go; so I will kill your firstborn son.’”^(G)

²⁴ At a lodging place on the way, the Lord met Moses^[a] and was about to kill^(H) him. ²⁵ But Zipporah^(I) took a flint knife, cut off her son’s foreskin^(J) and touched Moses’ feet with it.^[b] “Surely you are a bridegroom of blood to me,” she said. ²⁶ So the Lord let him alone. (At that time she said “bridegroom of blood,” referring to circumcision.)
