Isaiah 28:26-29

For he is rightly instructed; his God teaches him. Dill is not threshed with a threshing sledge, nor is a cart wheel rolled over cumin, but dill is beaten out with a stick, and cumin with a rod. Does one crush grain for bread? No, he does not thresh it forever; when he drives his cart wheel over it with his horses, he does not crush it. This also comes from the LORD of hosts; he is wonderful in counsel and excellent in wisdom.
