1By David, a psalm. The Lord said to my master, "Sit at My right, until I make your enemies a stool for your feet.”
2The staff of your strength the Lord will send from Zion, to rule amid your enemies.
3Your people [will come] willingly on the day of your campaign; because of your splendid sanctity from when you emerged from the womb, you still possess the dew of your youth.
4The Lord has sworn and will not regret: "You shall be a priest forever, just as Melchizedek!”
5My Lord is at your right; He has crushed kings on the day of His fury.
6He will render judgement upon the nations, and they will be filled with corpses; He will crush heads over a vast land.
7He will drink from the stream on the way, and so will hold his head high.


Please explain me the sage attribute some of of the tehilim to Melchizedek I want to know about it
