Isaiah 28:27-28

27After the harvest, the farmer knows how to remove seeds from dill or from cummin. He will not pull a heavy iron weight over dill. He will not run the wheels of a cart over cummin. Instead, he will hit them with a light stick.

28When he crushes grain to make flour for bread, he does not do it for a long time. He drives the wheels of his cart over the grain, but he does not let his horses crush it.
