Isaiah 28:26-28

Amplified Bible, Classic Edition

²⁶ [And he trains each of them correctly] for his God instructs him correctly and teaches him.

²⁷ For dill is not threshed with a sharp threshing instrument, nor is a cartwheel rolled over cummin; but dill is beaten off with a staff, and cummin with a rod [by hand].

²⁸ Does one crush bread grain? No, he does not thresh it continuously. But when he has driven his cartwheel and his horses over it, he scatters it [tossing it up to the wind] without having crushed it.
