'House of David' in the Bible

Then Solomon brought the daughter of Pharaoh up from the City of David into the house (palace) he had built for her, for he said, “My wife shall not live in the house of David king of Israel, because the places where the ark of the Lord has entered are holy.”

And Israel has rebelled against the house of David to this day.

Yet the Lord would not destroy the house of David because of the covenant which He had made with David, and because He had promised to give a lamp to him and to his sons forever.
