'House of David' in the Bible

LORD also shall save the tents of Judah first, that the glory of the house of David and the glory of the inhabitants of Jerusalem not be magnified above Judah.

In that day LORD shall defend the inhabitants of Jerusalem. And he who is feeble among them at that day shall be as David, and the house of David shall be as God, as the agent of LORD before them.

And I will pour upon the house of David, and upon the inhabitants of Jerusalem, the spirit of grace and of supplication. And they shall look to me whom they have pierced. And they shall mourn for him, as [a man] mourns for his only

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.
