'Widow' in the Bible

if you no longer oppress the foreigner, the fatherless, and the widow and no longer shed innocent blood in this place or follow other gods, bringing harm on yourselves,

This is what the Lord says: Administer justice and righteousness. Rescue the victim of robbery from the hand of his oppressor. Don’t exploit or brutalize the foreigner, the fatherless, or the widow. Don’t shed innocent blood in this place.
