• Newari: “But if the LORD does something entirely new and if the earth opens its mouth and swallows them up with all their property, and they go down alive to Sheol, you will know that these people have despised God."” (Source: Newari Back Translation)
• Hiligaynon: “But if the LORD will-do miraculous/amazing thing, and the ground will-split and will-swallow them alive together with all their properties, and they will-go to the depths there in the place of the dead-ones, you (plur.) will-know that these people have-rejected the LORD.’” (Source: Hiligaynon Back Translation)
• English: “But if Yahweh does something that has never happened before, if he causes the ground that is under their feet to open up and swallow these men and their families and all their possessions, and they fall into the opening and are buried while they are still alive, then you will know that these men have insulted Yahweh.’” (Source: Translation for Translators)
