Isaiah 28:27-29

A farmer doesn’t use heavy boards to crush dill; he doesn’t use a wagon wheel to crush cumin. He uses a small stick to break open the dill, and with a stick he opens the cumin. The grain is ground to make bread. People do not ruin it by crushing it forever. The farmer separates the wheat from the chaff with his cart, but he does not let his horses grind it. This lesson also comes from the LORD All-Powerful, who gives wonderful advice, who is very wise.
