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.
It seems the signs that are being referred to in the above text had been performed by Moses at mount Horeb.
But what is a little bit baffling is that the subject of the above text seems to be Aaron not Moses
It's not clear who performed these signs in front of the Israelites?
