English Standard Version
Chapter 4
23 and I say to you, “Let my son go that he may serve me.” If you refuse to let him go, behold, I will kill your firstborn son.’”
24 At a lodging place on the way the LORD met him and sought to put him to death.
25 Then Zipporah took a flint and cut off her son’s foreskin and touched Moses’ feet with it and said, “Surely you are a bridegroom of blood to me!”
26 So he let him alone. It was then that she said, “A bridegroom of blood,” because of the circumcision.
