You will sow much seed in the field but you will harvest little, because locusts will devour it. You will plant vineyards and cultivate them but you will not drink the wine or gather the grapes, because worms will eat them. You will have olive trees throughout your country but you will not use the oil, because the olives will drop off. You will have sons and daughters but you will not keep them, because they will go into captivity. Swarms of locusts will take over all your trees and the crops of your land. (Deuteronomy 28:38-48)
