John Wesley on Numbers 26:10

With Korah - According to this translation Korah was not consumed by fire with his two hundred and fifty men, but swallowed up by the earth. But others rather think he was devoured by the fire, and render these words, and the things of Korah, or belonging to Korah, namely, his tent and goods, and family, children excepted, as here follows. A sign - God made them a monument or example, to warn others not to rebel against God, or magistracy, nor to usurp the priestly office.
