Deuteronomy 11:6-8

American Standard Version

⁶ and what he did unto Dathan and Abiram, the sons of Eliab, the son of Reuben; how the earth opened its mouth, and swallowed them up, and their households, and their tents, and every living thing that followed them, in the midst of all Israel: ⁷ but your eyes have seen all the great work of Jehovah which he did.

⁸ Therefore shall ye keep all the commandment which I command thee this day, that ye may be strong, and go in and possess the land, whither ye go over to possess it;
