Numbers 16:24 - Albert Barnes' Notes on the Bible

The tent, “the tabernacle” of Korah, as a Kohathite, stood on the south side of the tabernacle of the Lord; and those of Dathan and Abiram, as Reubenites, in the outer line of encampment on the same side. Yet though the tents of these three were thus contiguous, they did not share the same fate. Korah and his company who dared to intrude themselves on the priestly office were destroyed by fire from the Lord at the door of the tabernacle of the Lord Numbers 16:35; the Reubenites, who had reviled Moses for the failure of the promises about the pleasant land, were suddenly engulfed while standing at their own tent-doors in the barren wilderness Numbers 16:31-33.
