Deuteronomy 11:5-7

It was not your children who saw what he did for you in the wilderness until you arrived at this place, and what he did to Dathan and Abiram, sons of Eliab the Reubenite, when the earth opened its mouth right in the middle of all Israel and swallowed them up with their households, their tents and every living thing that belonged to them. But it was your own eyes that saw all these great things the LORD has done.
