'Grain' in the Bible

But they don't know the thoughts of the LORD, and they don't understand his tactics, for he will gather them like harvested grain to his threshing floor.

Up! and let the grain be crushed, O daughter of Zion, for I will make your horn iron and your feet brass, and a number of peoples will be broken by you, and you will give up their increase to the Lord and their wealth to the Lord of all the earth.

“Are there not still treasures gained by wickednessIn the house of the wicked,And a short (inaccurate) measure [for grain] that is cursed?

You will put in seed, but you will not get in the grain; you will be crushing olives, but your bodies will not be rubbed with the oil; and you will get in the grapes, but you will have no wine.
