'House' in the Bible

But there will be a deliverance on Mount Zion,and it will be holy;the house of Jacob will dispossessthose who dispossessed them.

Then the house of Jacob will be a blazing fire,and the house of Joseph, a burning flame,but the house of Esau will be stubble;Jacob will set them on fire and consume Edom.Therefore no survivor will remainof the house of Esau,for the Lord has spoken.
