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, `Thus says Yahweh, 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 son, your firstborn.`"
24It happened on the way at a lodging place, that Yahweh met him 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.
