'House of Israel' in the Bible

It happened, from the day that the ark stayed in Kiriath Jearim, that the time was long; for it was twenty years: and all the house of Israel lamented after Yahweh.

Samuel spoke to all the house of Israel, saying, "If you do return to Yahweh with all your heart, then put away the foreign gods and the Ashtaroth from among you, and direct your hearts to Yahweh, and serve him only; and he will deliver you out of the hand of the Philistines."
