'Grain' in the Bible

Put your servants to the test for ten days; let them give us grain for our food and water for our drink.

So the keeper regularly took away their meat and the wine which was to have been their drink, and gave them grain.

Then the iron and the earth, the brass and the silver and the gold, were smashed together, and became like the dust on the floors where grain is crushed in summer; and the wind took them away so that no sign of them was to be seen: and the stone which gave the image a blow became a great mountain, covering all the earth.
