Commentary for Deuteronomy 11:6

בקרב כל ישראל [AND THE EARTH SWALLOWED THEM UP] IN THE MIDST OF ALL ISRAEL — Wherever one of them fled the earth was riven beneath him and swallowed him up. This is the view of R. Judah. Rabbi Nehemiah said to him: But is it not already stated, (Numbers 16:32) “And the earth opened its mouth”, and it does not state “its mouths”? Whereupon he (R. Judah) asked him: “But how, then, can I explain the words: “in the midst of all Israel” (if there was but one spot at which they were swallowed up, as you suggest Scripture states by the word פיה, “its mouth”)? He replied to him: you can reconcile the two texts by assuming that the earth became a declivity, — something like a funnel, — and wherever it was that one of them happened to be, he rolled down until he reached the place where the fissure was (cf. Yalkut Shimoni on Torah 752).

He mentions and what He did unto Dathan and A biram,²⁹⁸Verse 6. but did not mention of Korach and his company that a fire came forth from before the Eternal and consumed them, because it is a prohibition of the Torah for a stranger [non-priest] to approach [the Sanctuary] to burn incense,²⁹⁹See Ramban to Numbers 17:5 (Vol. IV, pp. 185-186). such a transgressor being punished in all future generations, as happened also to King Uzziah;³⁰⁰II Chronicles 26:19. therefore he did not enumerate it among the signs in the wilderness.

כל היקום..בקרב כל ישראל, "every substance…in the midst of all Israel." This means that the earth swallowed even the substances belonging to Datan and Aviram which were not in the vicinity of their owners wherever they happened to be at that moment. Bamidbar Rabbah 18,13 claims that even a needle was included in this statement.
