'Widow' in the Bible

And Jeroboam the son of Nebat, an Ephrathite of Zeredah, Solomon's servant (whose mother's name was Zeruah, a widow woman), even he lifted up his hand against the king.

Arise, go to Zarephath, which is by Zidon, and abide there: behold, I have commanded a widow woman there to maintain thee.

And he arose and went to Zarephath; and when he came to the entrance of the city, behold, a widow woman was there gathering sticks. And he called to her and said, Fetch me, I pray thee, a little water in a vessel, that I may drink.

And he cried to Jehovah and said, Jehovah, my God, hast thou also brought evil upon the widow with whom I sojourn, by slaying her son?
