Parallel
Numbers 26:10
Brenton's English Septuagint · Berean Standard Bible
And the earth opened her mouth, and swallowed up them and Core, when their assembly perished, when the fire devoured the two hundred and fifty, and they were made a sign.
And the earth opened its mouth and swallowed them along with Korah, whose followers died when the fire consumed 250 men. They serve as a warning sign.
