Isaiah 28:26-28

International Standard Version

²⁷ For caraway is not threshed with a sharp sledge,
    nor is a cart wheel rolled over cumin.
Instead, caraway is winnowed with a stick,
    and cumin with a rod.
²⁸ It^[b] must be ground;^[c]
    one cannot keep threshing it forever.
Even if he drives his cart^[d] and horses over it,
    he cannot crush it.
