'Wheat' in the Bible

Now the men of Beth-shemesh were gathering their wheat harvest in the valley, and they looked up and saw the ark and rejoiced to see it.

Is it not [the beginning of the] wheat harvest today? I will call to the Lord and He will send thunder and rain; then you will know [without any doubt], and see that your evil which you have done is great in the sight of the Lord by asking for yourselves a king.”
