'Harvest' in the Bible

They of Beth Shemesh 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 them to him for captains of thousands, and captains of fifties; and [he will set some] to plow his ground, and to reap his harvest, and to make his instruments of war, and the instruments of his chariots.

Isn't it wheat harvest today? I will call to Yahweh, that he may send thunder and rain; and you shall know and see that your wickedness is great, which you have done in the sight of Yahweh, in asking for a king."
