21 And the Lord said unto Moses, When thou goest to return into Egypt, see that thou do all those wonders before Pharaoh, which I have put in thine hand, and I will prosper thee; but Pharaoh will harden his heart, and he will not let the people go.
22 And thou shalt say unto Pharaoh, Thus saith the Lord, Israel is my son, even my firstborn;
23 And I say unto thee, Let my son go, that he may serve me; and if thou refuse to let him go, behold, I will slay thy son, even thy firstborn.
24 And it came to pass, that the Lord appeared unto him as he was in the way, by the inn. The Lord was angry with Moses, and his hand was about to fall upon him to kill him; for he had not circumcised his son.
25 Then Zipporah took a sharp stone and circumcised her son, and cast the stone at his feet, and said, Surely thou art a bloody husband unto me.
26 And the Lord spared Moses and let him go, because Zipporah, his wife, circumcised the child. And she said, Thou art a bloody husband. And Moses was ashamed, and hid his face from the Lord, and said, I have sinned before the Lord.
27 And the Lord said unto Aaron, Go into the wilderness to meet Moses, and he went and met him, in the mount of God; in the mount where God appeared unto him; and Aaron kissed him.
28 And Moses told Aaron all the words of the Lord who had sent him, and all the signs which he had commanded him.
29 And Moses and Aaron went and gathered together all the elders of the children of Israel;
30 And Aaron spake all the words which the Lord had spoken unto Moses, and did the signs in the sight of the people.
31 And the people believed; and when they heard that the Lord had visited the children of Israel, and that he had looked upon their affliction, then they bowed their heads and worshiped.
