'Grape' in the Bible

This is what the Lord who rules over all said to me: "Those who remain in Israel will be like the grapes thoroughly gleaned from a vine. So go over them again, as though you were a grape harvester passing your hand over the branches one last time."

I will weep for the grapevines of Sibmah just like the town of Jazer weeps over them. Their branches once spread as far as the Dead Sea. They reached as far as the town of Jazer. The destroyer will ravage her fig, date, and grape crops.

If grape pickers came to pick your grapes, would they not leave a few grapes behind? If robbers came at night, would they not pillage only what they needed?
