The death of David did not mean the end of his glory and grandeur. It merely caused a change of scene. In the heavenly realm as on earth David ranks among the first. The crown upon his head outshines all others, and whenever he moves out of Paradise to present himself before God, suns, stars, angels, seraphim, and other holy beings run to meet him.
In the heavenly court-room a throne of fire of gigantic dimensions is erected for him directly opposite to the throne of God. Seated on this throne and surrounded by the kings of the house of David and other Israelitish kings, he intones wondrously beautiful psalms. At the end he always cites the verse: "The Lord reigns forever and ever," to which the archangel Metatron and those with him reply: "Holy, holy, holy, is the Lord of hosts!"
This is the signal for the holy Hayyot and heaven and earth to join in with praise. Finally the kings of the house of David sing the verse: "And the Lord shall be king over all; in that day shall the Lord be one, and His name one."
