NET

26 I invoke heaven and earth as witnesses against you today that you will surely and swiftly be removed from the very land you are about to cross the Jordan to possess. You will not last long there because you will surely be annihilated.

Darby

26 I call heaven and earth to witness against you this day, that ye shall soon utterly perish from off the land whereunto ye pass over the Jordan to possess it: ye shall not prolong your days on it, but shall be utterly destroyed.

KJV

26 I call heaven and earth to witness against you this day, that ye shall soon utterly perish from off the land whereunto ye go over Jordan to possess it; ye shall not prolong [your] days upon it, but shall utterly be destroyed.
