The answer
The children of Korah did not die; for, if you read Numbers 16:27 closely; it states "So they got away from around the tents of Korah, Dathan, and Abiram; and Dathan and Abiram came out and stood at the door of their tents, with their wives, their sons, and their little children." It is only the sons and the little ones of Dathan and Abiram who are mentioned. Since there is no mention of the children of Korah, they must have escaped; while those of Dathan and Abiram perished with their fathersAnswered by His Eminence Metropolitan Youssef (opens in a new tab)
