Isaiah 28:28

26 For his God instructs and teaches him properly.

27 Surely caraway is not threshed with a sledge, and the wheel of a cart is not rolled over the cumin. But caraway is beaten out with a stick, and cumin with a rod.

Grain for bread must be ground, but it is not endlessly threshed. Though the wheels of the cart roll over it, the horses do not crush it.

29 This also comes from the LORD of Hosts, who is wonderful in counsel and excellent in wisdom.

Do read the surrounding verses too, because the context often says more than a single verse.
