Deuteronomy 11:6BSB·traditional attribution

and what He did in the midst of all the Israelites to Dathan and Abiram, the sons of Eliab the Reubenite, when the earth opened its mouth and swallowed them, their households, their tents, and every living thing that belonged to them.

Matthew Henry Presbyterian @wholebiblehenry

Because God has made thee as the stars of heaven for multitude (so the preceding chapter concludes), therefore thou shalt love the Lord thy God (so this begins). Those whom God has built up into families, whose beginning was small, but whose latter end greatly increases, should use that as an argument with themselves why they should serve God.
