Charles H. Spurgeon on Psalms 106:17

Dathan and Abiram only are mentioned, and this in strict agreement with Nu 26:11, where it is said, "the children of Korah died not." And the same thing is at least implied in Nu 16:27, where it is said, that, just before the catastrophe took place, "Dathan and Abiram" (there is no mention of Korah) "came out and stood in the door of their tents." See this noticed and accounted for in Blunt's Veracity of the Books of Moses, Part 1, 20 pounds, 86. J.J. Stewart Perowne.
