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

and Saul dieth, and his three sons, and all his house, together they died.

So death overtook Saul and his three sons; all his family came to an end together.

Therefore, Saul died, and his three sons passed away, and his entire house fell, together.

All his house died together - Not the whole of his family, nor even "all his sons" (see 2-Samuel 2:8-15; 2-Samuel 3:6-15; 2-Samuel 4:1-12). The phrase is perhaps an abbreviation of the expression in the parallel passage of Samuel 1-Samuel 31:6.

So Saul died - and all his house - Every branch of his family that had followed him to the war was cut off; his three sons are mentioned as being the chief. No doubt all his officers were slain.

Saul died, and his three sons, and all his house--his sons and courtiers who were there engaged in the battle. But it appears that Ish-bosheth and Mephibosheth were kept at Gibeah on account of their youth.

His house - All his children, then present with him, namely, his three sons, for Ishbosheth and Mephiboshieth were not slain.
