'Glean' in the Bible

When you gather the grapes of your vineyard, you must not glean what is left. What remains will be for the foreigner, the fatherless, and the widow.

They gather their fodder in the fieldand glean the vineyards of the wicked.

This is what the Lord of Hosts says:Glean the remnant of Israelas thoroughly as a vine.Pass your hand once more like a grape gathererover the branches.
