'House of Israel' in the Bible

All of Israel will mourn for him, and they will bury him. This one alone will come to a tomb for Jeroboam, because a good thing has been found in him by Yahweh the God of Israel in the house of Israel.

And his servants said unto him, Behold now, we have heard that the kings of the house of Israel are merciful kings: let us, I pray thee, put sackcloth on our loins, and ropes upon our heads, and go out to the king of Israel: peradventure he will save thy life.
