Psalm 110 is often used to talk about Jesus since it refers to *two* lords--and also that David, the alleged author, is regarding this lord as higher than himself.
However, I believe this is not the case.
First, the Psalm is "Of David". It does not mean it is David himself. It could probably have been made by somebody's in David's court.
The phrase "Sit on my right hand" does not refer to David literally sitting on the right hand of God, probably, but is mere metaphor, in much the same way Yahweh is shown as 'sneezing' the Sea of Reeds in Exodus.
The "Priest in the Order of Melchediek" refers to a king in GENESIS who served as both priest and king of Salem, pre-Jewish Jerusalem, who apparentally also worshipped Yahweh(How he came upon such a revelation is not elaborated on). David, like Melchediek, is a king who performs priestly rites and rules Jerusalem. Hence "being in the same order". Christians maimed this, saying the Melchediek order superseded the Levites and also because Melchediek was somehow born spiritually and immortal. The reason given for this was because he was given no genealogy. Gee, I suppose that means that every character with no genealogy in the bible must therefore be immortal and transcendent....
