But if the LORD brings about something unprecedented, and the earth opens its mouth and swallows them and all that belongs to them so that they go down alive into Sheol, then you will know that these men have treated the LORD with contempt.”
KJV
But if the LORD make a new thing, and the earth open her mouth, and swallow them up, with all that [appertain] unto them, and they go down quick into the pit; then ye shall understand that these men have provoked the LORD.
ASV
But if Jehovah make a new thing, and the ground open its mouth, and swallow them up, with all that appertain unto them, and they go down alive into Sheol; then ye shall understand that these men have despised Jehovah.
