It is recorded at Deuteronomy 28:20: "Jehovah will send upon you the curse, confusion and rebuke in every undertaking of yours that you try to carry out until you have been annihilated and you have perished in a hurry, because of the badness of your practices in that you have forsaken me."
20 "Yehovha u ta rhumela ndzhukano ehenhla ka wena,+ ku pfilunganyeka+ ni ku tshinyiwa+ entirhweni wun'wana ni wun'wana wa wena lowu u ringetaka ku wu hetisisa, ku fikela loko u lovisiwile naswona u lovile hi ku hatlisa hikwalaho ka vubihi bya mahanyelo ya wena, hikuva u ndzi fularhelile.+
