Who was the wise wife of the foolish Nabal, who later married David?

Answer: Abigail

Abigail was intelligent and beautiful, while Nabal was harsh and evil. After Nabal died, David asked her to become his wife.

“His name was Nabal, and his wife’s name was Abigail. She was an intelligent and beautiful woman, but her husband, a Calebite, was harsh and evil in his dealings.”— 1 Samuel 25:3 (BSB)
