Exodus 4:27-31

27The Lord said to Aaron, "Go into the wilderness to meet Moses." So he went and met him at the mountain of God and kissed him.

28And Moses told Aaron all the words of the Lord with which he had sent him to speak, and all the signs that he had commanded him to do.

29Then Moses and Aaron went and gathered together all the elders of the people of Israel.

30Aaron spoke all the words that the Lord had spoken to Moses and did the signs in the sight of the people.

31And the people believed; and when they heard that the Lord had visited the people of Israel and that he had seen their affliction, they bowed their heads and worshiped.
