Psalm 110:1 "The LORD says to my lord:
The Hebrews were forbidden to utter the NAME of God, the tetragrammaton
YHWH, so they always substituted another word, like LORD.
In Aramaic, the word that is translated to LORD (in caps) is Adonai, a word that is used nowhere in the bible to refer to ANYONE or ANYTHING other than the Creator/Father/God
The lower case "lord" is translated from the word Adoni meaning king, master, even husband. All referring to a human.
Trinitarians use Psalm 110:1 to show that (as they believe) there are three parts to God, who talk to each other.
That is not the case, as in this instance God was talking to a human.
