'Olive tree' in the Bible

Yet gleanings will be left there, like the shaking of an olive tree, two or three olives in the top of the uppermost bough, four or five in the outermost branches of a fruitful tree," says Yahweh, the God of Israel.

For it will be so in the midst of the earth among the peoples, as the shaking of an olive tree, as the gleanings when the vintage is done.
