'House of David' in the Bible

And it will be announced to the house of David, saying, Aram rested upon Ephraim; and his heart will move to and fro and the heart of his people, as the woods of the forest moved from the face of the wind.

And he will say, Hear ye now, house of David; is it small for you to weary men, but will ye weary God also

And I gave the key of the house of David upon his shoulder, and he opened and none shut, and he shut and none opened.
