'House' in the Bible

But on Mount Zion there will be an escape, and it will be holy, and the house of Jacob will take possession [of] their dispossessors.

And the house of Jacob will be a fire and the house of Joseph a flame, and the house of Esau stubble; and they will set them on fire and will consume them. And there will not be a survivor for the house of Esau," for Yahweh has spoken.
