Matthew Poole and continuators on 1 Chronicles 10:6

6 So Saul died, and his three sons, and all his house died together.

i. e. All his Children, to wit, then present with him, namely, his three sons; as it is expressed, 1 Sam. 31. 6. For it is evident that Ishbosheth and Mephibosheth were not slain. But nothing is more common in Scripture and all Authors, than to understand all of a great and most considerable part.
