'Wheat' 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.

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."
