'Grapes' in the Bible

Ye shall know them by their fruits. Do men gather grapes of thorns, or figs of thistles?

For every tree is known by his own fruit. For of thorns men do not gather figs, nor of a bramble bush gather they grapes.

And another angel came out from the altar, which had power over fire; and cried with a loud cry to him that had the sharp sickle, saying, Thrust in thy sharp sickle, and gather the clusters of the vine of the earth; for her grapes are fully ripe.
