'Throne of David' in the Bible

Then Solomon was seated upon the throne of David his father; and his kingdom was established greatly.

Now therefore, as the LORD liveth, who hath established me, and set me on the throne of David my father, and who hath made me a house, as he promised, Adonijah shall be put to death this day.

And king Solomon shall be blessed, and the throne of David shall be established before the LORD for ever.
