22 Then say to the king, ‘This is what the Lord says: Israel is my firstborn son.
23 I told you to let my son go so he may worship me. But you refused to let Israel go, so I will kill your firstborn son.’ ”
24 As Moses was on his way to Egypt, he stopped at a resting place for the night. The Lord met him there and tried to kill him.
25 But Zipporah took a flint knife and circumcised her son. Taking the skin, she touched Moses’ feet with it and said to him, “You are a bridegroom of blood to me.”
26 She said, “You are a bridegroom of blood,” because she had to circumcise her son. So the Lord let Moses alone.
27 Meanwhile the Lord said to Aaron, “Go out into the desert to meet Moses.” When Aaron went, he met Moses at Sinai, the mountain of God, and kissed him.
28 Moses told Aaron everything the Lord had said to him when he sent him to Egypt. He also told him about the miracles which the Lord had commanded him to do.
