Exodus 4:28-31

And 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. Then Moses and Aaron went and gathered together all the elders of the people of Israel. Aaron spoke all the words that the LORD had spoken to Moses and did the signs in the sight of the people. And 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.
