'Harvest' in the Bible

Now the people of Beth-shemesh were gathering their wheat harvest in the valley. They looked up, saw the Ark, and rejoiced to see it.

He will appoint his officers over thousands and officers over fifties some will plow his fields, reap his harvest, and craft his war implements and equipment for his chariots.

Is it not the wheat harvest today? I'll call upon the LORD, and he will send thunder and rain. Then you will know and understand that you have done a great evil in the sight of the LORD by asking for a king for yourselves."
