The Gas now in Ghana once lived at North-Africa. Part of them lived in the Southern part of Mizraim. Gas also lived at the end of River Nile, which makes their main vocational job fishing and hunting.
They were released by Pharaoh Ammenhotep the second in Israel. That was how they started dividing themselves; and can be found in Africa mostly. Some proof that the Gas were once with the Israelites are their rites, traditions, etc.
