'Widow's' in the Bible

Thou shalt not pervert the judgment of the stranger, or of the fatherless; and thou shalt not take in pledge a widow's garment.

He was a widow's son of the tribe of Naphtali, and his father was a man of Tyre, a worker in brass; and he was full of wisdom and understanding and knowledge, to do all kinds of works in brass. And he came to king Solomon, and made all his work.

They drive away the ass of the fatherless, they take the widow's ox for a pledge;

The blessing of him that was perishing came upon me, and I caused the widow's heart to sing for joy.
