Yahweh will make the plague cling to you until it has consumed you off the land you are entering to possess.
In context
19Cursed are you when you come in, and cursed are you when you go out. 20Yahweh will send against you curses, confusion, and rebuke in everything you put your hand to, until you are destroyed and quickly perish, because of the evil of your deeds — because you have forsaken me. 21Yahweh will make the plague cling to you until it has consumed you off the land you are entering to possess. 22Yahweh will strike you with wasting disease, fever, and inflammation, with scorching heat and the sword, with blight and mildew — they will pursue you until you perish. 23The sky over your head will be bronze, and the earth beneath you iron.
