'House of Israel' in the Bible

And, when Rehoboam entered Jerusalem, he called together all the house of Judah and the tribe of Benjamin - a hundred and eighty thousand chosen men, able to make war, - to fight against the house of Israel, to bring back the kingdom to Rehoboam, son of Solomon.

And his servants said unto him, Lo! we pray thee, we have heard, of the kings of the house of Israel, that, kings known for lovingkindness, they are. Let us, we pray thee, put sackcloth upon our loins, and ropes about our head, and let us go forth unto the king of Israel, peradventure he will save alive thy soul.
