'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 (grain left after reaping) of your harvest.

‘When you reap the harvest of your land, you shall not reap to the edges of your field, nor gather the gleaning of your harvest; you are to leave them for the poor and for the stranger. I am the Lord your God.’”

“Yet gleanings will be left in the land [of Israel] like the shaking of the olive tree,Two or three olives on the topmost branch,Four or five on the [outermost] branches of the fruitful tree,”Declares the Lord, the God of Israel.
