1 Samuel 14:50

And the name of Saul's wife was Ahinoam, the daughter of Ahimaaz,.... Who very probably was the mother of all the above children, and therefore taken notice of; and Abarbinel conjectures that Ishbosheth was not a son of her's, but the son of Saul by another wife, and which he takes to be another reason why he is not mentioned here; but though Saul had a concubine, we nowhere read of his having another wife:

and the name of the captain of his host was Abner the son of Ner, Saul's uncle; not Abner, but Ner, was Saul's uncle; for Kish the father of Saul, and Ner, were brothers, as Josephus p says, and as appears from the next verse; and Abner was first cousin to Saul, whom he raised and advanced to be captain of his army, and a very valiant man he was: we hear of him again in this history, and in the beginning of David's reign.
