'House of David' in the Bible

The Lord also will save the tents of Judah first, so that the glory of the house of David and the glory of the inhabitants of Jerusalem will not be magnified above Judah.

In that day the Lord will defend the inhabitants of Jerusalem, and the one who is feeble among them in that day will be like David, and the house of David will be like God, like the angel of the Lord before them.

“I will pour out on the house of David and on the inhabitants of Jerusalem, the Spirit of grace and of supplication, so that they will look on Me whom they have pierced; and they will mourn for Him, as one mourns for an only son, and they will weep bitterly over Him like the bitter weeping over a firstborn.

The land will mourn, every family by itself; the family of the house of David by itself and their wives by themselves; the family of the house of Nathan by itself and their wives by themselves;

“In that day a fountain will be opened for the house of David and for the inhabitants of Jerusalem, for sin and for impurity.
