Numbers 26:11

“Notwithstanding, the children of Korah died not.] Neither of the pestilence, nor by fire, nor by the swallowing up of the earth; they not being in the counsel of their father, but followed the doctrine of Moses the prophet, as the Targum of Jonathan; they either disliked their father’s scheme, or, if they engaged with him in it, they repented and departed from him, and were not present when the judgments of God came upon him and his company; there were several of his posterity who were singers in the times of David, and to whom many of the psalms were sent to be sung. Ver. 12-14. The sons of Simeon, after their families, etc.] This tribe was next numbered, not only because Simeon was next to…”

“Notwithstanding the children of Korah died not--Either they were not parties to their father's crime, or they withdrew from it by timely repentance. His descendants became famous in the time of David, and are often mentioned in the Psalms [Psa 42:1; Psa 44:1; Psa 45:1; Psa 46:1; Psa 47:1; Psa 48:1; Psa 49:1; Psa 84:1; Psa 85:1; Psa 87:1; Psa 88:1], also in Ch1 6:22, Ch1 6:38.”

“The children of Korah died not - Compare Numbers 26:58. Samuel the prophet was of this family, and Heman, “the king’s seer” 1 Chronicles 6:22, 1Ch 6:33; 1 Chronicles 25:5. Several of the Psalms appear from the titles to have been composed for the sons of Korah: compare titles of Psalms 42:1-11; Psalms 44:0; Psalms 45:0, etc. return to 'Top of Page'”

“Died not - God being pleased to spare them, because they disowned their father's fact, and separated themselves both from his tent and company. Hence the sons of Korah are mentioned, Ch1 6:22, Ch1 6:38, and often in the book of Psalms. Numbers 26:12”

“It seems to be intimated in Num 16:27, Num 16:31-33, that the sons and the little ones of Korah, Dathan, and Abiram, were swallowed up; but the text here expressly affirms, that the children of Korah "died not;" and their descendants were famous even in David's time. On a close inspection, however, of Num 26:27, we shall find, that the sons and the little ones of Dathan and Abiram alone are mentioned. Num 16:5; Exo 6:24; Ch1 6:22-28; Psa 42:1, Psa 44:1, Psa 45:1, Psa 46:1, Psa 47:1 \*titles Psa 48:1, Psa 49:1, Psa 50:1 \*titles Numbers 26:12”
