Exodus 4:28-32

And Moses told Aaron all the words of the LORD who had sent him, and all the signs which he had commanded him.

And Moses and Aaron went and gathered together all the elders of the children of Israel:

And Aaron spake all the words which the LORD had spoken unto 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 children of Israel, and that he had looked upon their affliction, then they bowed their heads and worshipped.
