Aaron & Moses met each other in the wilderness and they were of course very happy to be united together. As instructed, Moses told Aaron all the words that God had said unto him and showed him the signs. These two brothers went to the elders of Israel & Aaron spoke the words of the Lord unto the people and showed them the two great signs, including the rod turning into a serpant and the hand becoming white as snow. And do you know that the people believed? Yes, they believed & worshipped the Lord.
