It is a fact that a grain of wheat must fall to the ground and die before it can grow and produce much more wheat. If it never dies, it will never be more than a single seed.
May the fields grow plenty of grain and the hills be covered with crops. May the fields be as fertile as Lebanon, and may people fill the cities as grass covers a field.
People grind grain to make flour, but they don’t grind it forever. As God does in punishing people, a worker might drive his wagon over the grain to remove the hulls, but he does not allow the horses to crush it.
