Leviticus 26:19-20

26:19 I will break your strong pride and make your sky like iron and your land like bronze. 26:20 Your strength will be used up in vain, your land will not give its yield, and the trees of the land will not produce their fruit.

Leviticus 26:26

26:26 When I break off your supply of bread, ten women will bake your bread in one oven; they will ration your bread by weight, and you will eat and not be satisfied.
