1 Samuel 25:41-44

She bowed low to the ground and responded, “I, your servant, would be happy to marry David. I would even be willing to become a slave, washing the feet of his servants!” Quickly getting ready, she took along five of her servant girls as attendants, mounted her donkey, and went with David’s messengers. And so she became his wife. David also married Ahinoam from Jezreel, making both of them his wives. Saul, meanwhile, had given his daughter Michal, David’s wife, to a man from Gallim named Palti son of Laish.
