'House of David' in the Bible

And Yahweh will save the tents of Judah first, so that the glory of the house of David and the glory of the inhabitants of Jerusalem may not be exalted over Judah.

On that day Yahweh will put a shield around the inhabitants of Jerusalem, and the one who stumbles among them on that day will be like David, and the house of David [will be] like God, like the angel of Yahweh, {before them}.

" 'I will pour on the house of David and on the inhabitants of Jerusalem a spirit of grace and supplication, and they will look to me whom they pierced, and they shall mourn over him, as one wails over an only child, and they will grieve bitterly over him as [one] grieves bitterly over a firstborn.

And the land shall mourn, {each clan by itself}; the clan of the house of David by itself, and their wives by themselves; the clan of the house of Nathan by itself, and their wives by themselves;

" 'On that day a well will be opened for the house of David and for the inhabitants of Jerusalem, {to cleanse them from sin and from impurity}.
