Exodus 4:26-30

So He left him alone. At that time she said, “You are a groom of blood”—because of the circumcision.

Now the Lord said to Aaron, “Go to meet Moses in the wilderness.” So he went and met him at the mountain of God and kissed him.

Moses told Aaron all the words of the Lord with which He had sent him, and all the signs that He had commanded him to do.

Then Moses and Aaron went and assembled all the elders of the sons of Israel;

and Aaron spoke all the words which the Lord had spoken to Moses. He then performed the signs in the sight of the people.
