Deuteronomy 11:6-7

6They did not see how he punished Dathan and Abiram, Eliab's sons, from Reuben's tribe. God caused the earth to open up in the middle of the Israelites' camp. These men fell down into the hole and they disappeared. Their families, their tents and everything that they had all disappeared in the hole.

7Remember that I am speaking to you, the people who have seen the Lord's powerful acts.
