Deuteronomy 30:17-18

But if you i heart turn away, so that you i will not hear, but shall be drawn away, and worship other gods, and serve them; I denounce unto you this day, that you 2f shall surely perish, [and that] you 2f shall not prolong [your] days upon the land, to which you i pass over Yarden [Descender] to go to possess it.
