'Threshed' in the Bible

For the dill is not threshed with a threshing instrument, neither is a cart-wheel turned about upon the cummin; but dill is beaten out with a staff, and cummin with a rod.

Thus saith Jehovah: For three transgressions of Damascus, and for four, I will not revoke my sentence, because they have threshed Gilead with threshing instruments of iron.
