'Gleanings' in the Bible

‘Now when you reap the harvest of your land, you shall not reap to the very corners of your field, nor shall you gather the gleanings of your harvest.

Yet gleanings will be left in it like the shaking of an olive tree,Two or three olives on the topmost bough,Four or five on the branches of a fruitful tree,Declares the Lord, the God of Israel.

For thus it will be in the midst of the earth among the peoples,As the shaking of an olive tree,As the gleanings when the grape harvest is over.

“If grape gatherers came to you,Would they not leave gleanings?If thieves came by night,They would destroy only until they had enough.

“If thieves came to you,If robbers by night—O how you will be ruined!—Would they not steal only until they had enough?If grape gatherers came to you,Would they not leave some gleanings?
