'Sweepings' in the Bible

Therefore the anger of the Lord has burned against His people,And He has stretched out His hand against them and has struck them down.And the mountains trembled, and their dead bodies lay like rubbish in the middle of the streets.In spite of all this God’s anger is not turned away,But His hand is still stretched out [in judgment].

And peoples have been as burnings of lime, Thorns, as sweepings, with fire they burn.

that we may buy the poor for silver, and the needy for a pair of shoes, and sell the sweepings with the wheat?'"
