'Grain' in the Bible

Now one day, when the child was older, he went out to his father to where the grain was being cut.

And he said, If the Lord does not give you help, where am I to get help for you? from the grain-floor or the grape-crusher?

Till I come and take you away to a land like yours, a land of grain and wine, a land of bread and vine-gardens, a land of oil-giving olives and of honey, so that life and not death may be your fate. Give no attention to Hezekiah when he says to you, The Lord will keep us safe.

And this will be the sign to you: you will get your food this year from what comes up of itself; and in the second year from the produce of the same; and in the third year you will put in your seed and get in the grain and make vine-gardens and take of their fruit.
