'Grapes' in the Bible

Now the angel of the Lord came and took his seat under the oak-tree in Ophrah, in the field of Joash the Abiezrite; and his son Gideon was crushing grain in the place where the grapes were crushed, so that the Midianites might not see it.

And he said unto them, What have I done now in comparison of you? Is not the gleaning of the grapes of Ephraim better than the vintage of Abiezer?

And they went out into the fields, and gathered their vineyards, and trode the grapes, and made merry, and went into the house of their god, and did eat and drink, and cursed Abimelech.
