'Gleanings' in the Bible

Furthermore, when you harvest the produce of your land, you are not to harvest all the way to the corners of your field or gather the gleanings of your harvest. Leave them for the poor and resident alien. I am the LORD your God."

Nevertheless, gleanings will remain in Israel, as when an olive tree is beaten two or three ripe olives left in the topmost branches, four or five left among the branches of a fruit-filled tree," declares the LORD God of Israel.

So it will be on the earth and among the nations as when an olive tree is beaten, or as gleanings when the grape harvest has ended."

If the grape harvesters came to you, would they not leave gleanings? If thieves came at night, they would destroy only until they had enough.
