'Harvest' in the Bible

And they of Bethshemesh were reaping their wheat harvest in the valley: and they lifted up their eyes, and saw the ark, and rejoiced to see it.

And he will appoint him captains over thousands, and captains over fifties; and will set them to ear his ground, and to reap his harvest, and to make his instruments of war, and instruments of his chariots.

Is it not wheat harvest to day? I will call unto the LORD, and he shall send thunder and rain; that ye may perceive and see that your wickedness is great, which ye have done in the sight of the LORD, in asking you a king.
