'Lamp' in the Bible

Please, let us make a small, fully-walled upper room [on the housetop] and put a bed there for him, with a table, a chair, and a lampstand. Then whenever he comes to visit us, he can turn in there.”

Yet for the sake of His servant David the Lord was not willing to destroy Judah, since He had promised to give him a lamp (enthroned descendant) through his sons always.
