'Widow' in the Bible

So David went there with his two wives, Ahinoam the Jezreelite and Abigail, the widow of Nabal the Carmelite.

his second was Chileab,by Abigail, the widow of Nabal the Carmelite;the third was Absalom,son of Maacah the daughter of King Talmai of Geshur;

“What’s the matter?” the king asked her.“To tell the truth, I am a widow; my husband died,” she said.
