Isaiah 28:28

28 Grain is crushed for bread, but one does not thresh it forever; one drives the cart wheel and horses over it, but does not pulverize it.

Isaiah 28:28 In-Context

26 For they are well instructed; their God teaches them.
27 Dill is not threshed with a threshing sledge, nor is a cart wheel rolled over cummin; but dill is beaten out with a stick, and cummin with a rod.
28 Grain is crushed for bread, but one does not thresh it forever; one drives the cart wheel and horses over it, but does not pulverize it.
29 This also comes from the Lord of hosts; he is wonderful in counsel, and excellent in wisdom.
