'Widow's' in the Bible

"Don't deny justice to a foreigner or to an orphan, nor take a widow's garment as collateral for a loan.

The house of the proud the LORD will demolish, but he will protect the widow's boundary line.

Learn to practice what is good; seek justice, alleviate oppression, defend orphans in court, and plead the widow's case.

Your princes are rebels and companions of thieves. All of them are lovers of bribes and are runners after gifts. They don't bring justice to orphans, and the widow's case never comes up for review in their court."
