'House of David' in the Bible

And Jehovah shall save the tents of Judah first, that the glory of the house of David and the glory of the inhabitants of Jerusalem be not magnified over Judah.

In that day will Jehovah defend the inhabitants of Jerusalem; and he that stumbleth among them at that day shall be as David; and the house of David as God, as the Angel of Jehovah before them.

And I will pour upon the house of David and upon the inhabitants of Jerusalem the spirit of grace and of supplications; and they shall look on me whom they pierced, and they shall mourn for him, as one mourneth for an only son, and shall be in bitterness for him, as one that is in bitterness for his firstborn.

And the land shall mourn, every family apart: the family of the house of David apart, and their wives apart; the family of the house of Nathan apart, and their wives apart;

In that day there shall be a fountain opened to the house of David and to the inhabitants of Jerusalem for sin and for uncleanness.
