'House of Israel' in the Bible

As for the vineyard of the LORD of Hosts, it is the house of Israel, and whole Judah his fair planting. Of these he looked for equity, but see there is wrong; for righteousness, lo, it is but misery.

The people shall take them, and carry them home to their own land. And the house of Israel shall have them in possession for servants and maidens in the land of the LORD. They shall take those prisoners, whose captives they had been afore: and rule those that had oppressed them.
