'Widow's' in the Bible

You shall not wrest the justice [due] to the foreigner, [or] to the fatherless, nor take the widow's clothing to pledge;

They drive away the donkey of the fatherless, and they take the widow's ox for a pledge.

the blessing of him who was ready to perish came on me, and I caused the widow's heart to sing for joy.

Yahweh will uproot the house of the proud, but he will keep the widow's borders intact.
