Mambo ya Walawi 26 : 20 Leviticus chapter 26 verse 20

na nguvu zenu mtazitumia bure; kwa kuwa nchi yenu haitazaa mazao yake, wala miti ya nchi haitazaa matunda yake.
soma Mlango wa 26

and your strength will be spent in vain; for your land won't yield its increase, neither will the trees of the land yield their fruit.
