Isaiah 28:27-29

27Caraway is not threshed with a sledge, nor is the wheel of a cart rolled over cumin; caraway is beaten out with a rod, and cumin with a stick.

28Grain must be ground to make bread; so one does not go on threshing it forever. The wheels of a threshing cart may be rolled over it, but one does not use horses to grind grain.

29All this also comes from the Lord Almighty, whose plan is wonderful, whose wisdom is magnificent.
