That comes from Psalm 45, most likely to Solomon first,
Solomon? God will address Solomon “Your throne, Oh God”? Solomon got more gods that any pagans during his time – 1King 11:1-6. “One greater than Solomon is here -Matthew 12:42”, that is, the Lord Jesus Christ, the Son of David, according to the flesh –Romans 1:3
foreshadowing Jesus second. But definitely to a KING of Israel or Judah first.
Psalm 45 is the one the description of the Davidic covenant [Isa 55:3, 2Samuel 7:12-16, Gen 49:10 “the scepter shall not depart from Judah”, Luke 1:31-33] that God made with king David in 2Samuel 7:11-16.
That KING was not God was he, so why is the author calling him, "elohim?" [OH] GOD? Because "elohim" in context here is one anointed or APPOINTED of God, sir.
1) Instead of dealing with the scripture as written, you are second guessing the author
Mt 22:41 While the Pharisees were gathered together, Jesus asked them,
Mt 22:42 “What do you think about the Christ ? Whose son is he?” “The son of David,” they replied.
The Lord Jesus is the Son of David according to the flesh [Romans 1:3] from the line of Judah, from the Davidic covenant, the Messiah. See John 1:14 “And the WORD became flesh”. IOW, “And the WORD was God –v1” “became flesh –v14” according to the Davidic covenant and that’s how he became the “Son of David” that was prophesied all the way back from Genesis 3:15, Gen 49:10 to Luke 1:31-33 to Paul’s Romans 1:3-4.
As you can read king Solomon is nowhere in the picture because “One greater than Solomon is here -Matthew 12:42”, the Lord Jesus Christ.
Mt 22:43 He said to them, “How is it then that David, speaking by the Spirit, calls him ‘Lord’? For he says,
Mt 22:44 “ ‘The Lord said to my Lord: “Sit at my right hand until I put your enemies under your feet.” ’
Who is this “Lord” in Psalm 110:1? According to your own interpretation, a “master”, or “adonee”, means: just an ordinary mortal human being like us.
Now, the question is this
Mt 22:45 If then David calls him ‘Lord,’ how can he be his son?”
How can He, the Lord Jesus, be David’s Son according to the Davidic covenant, and at the same time be his “Lord” according to Psalm 110:1?
What king David saw or have foreseen with the help of the Holy Spirit or “speaking by the Spirit” in Psalm 110:1 was the ascension of the Lord Jesus Christ at the right hand of God the Father in heaven.
Stephen was an eyewitness of the ascended LORD/ADNY Christ in,
Ac 7:55 But he, being full of the Holy Spirit, looked up stedfastly into heaven, and saw the glory of God, and Jesus standing on the right hand of God,
This is what the Lord Jesus was telling to the Jews in
Mt 26:63 But Jesus remained silent. The high priest said to him, “I charge you under oath by the living God: Tell us if you are the Christ, the Son of God.”
Mt 26:64 “Yes, it is as you say,”Jesus replied. “But I say to all of you: In the future you will see the Son of Man sitting at the right hand of the Mighty One and coming on the clouds of heaven.”
Now, according to your own interpretation an “adonee/master” cannot be God.
Isaiah 21:16 Dead Sea Scroll VERSION: For thus has the
Lord(ADNY/Hebrew/DSS Version) said to me, Within a year, according to the years of a hireling, and all the glory of Kedar shall fail;
Here Isaiah was talking about the “LORD” God and not just a “master” or just a mortal man.
In the DSS we read the word “LORD” as “ADNY” no vowel points. IOW, if we want to correct the Masoretic –with vowel points- text we would compare it to DSS, meaning: the older the text the better.
IOW, there is no VOWEL POINTS in the ancient Hebrew text and the dead sea scroll of Isaiah’ 21:16 where it says “Lord” as “ADNY” as “God” is the same as the one in Psalm 110:1 where the “Lord/ADNY” REFERRING TO THE Lord Jesus Christ was change BY THE MASORITES to “adoni” which translate to “master” and therefore became your own interpretation as well.
IOW again, your own interpretation of “adonee/master” in Psalm 110:1 and Matthew 22:44, on which you refer it ALSO to the Lord Jesus Christ as a mortal human being, IF compared to Isaiah 21:16 –DSS where the word “ADNY/LORD” –NO VOWEL POINTS- where it was referred to God Himself, IS NOT EXEGITICALLY VALID or YOUR OWN INTERPRETATION IS NOT EXEGITACALLY VALID AT ALL BASED ON THE SCRIPTURES.
IOW, there was no “adoni/master” in the original Hebrew text base on the Dead Sea Scroll, but “ADNY” WHICH MEANS THE “LORD” OR Jehovah.
ALL THIS JUST PROVED THAT THE LORD JESUS IS GOD.
So, when the God the Father says to His Son, “Thy Throne, Oh God” in Hebrews 1:8 you have to go all the way back to Genesis, to the Davidic Covenant in 2Sa 7:12-16, the Covenant that God made with king David about the Messiah from the tribe of Judah, to Isaiah, all the way to Paul’s epistles, and to Hebrews where it says “Thy Throne, Oh God” to prove your case.[/QUOTE]
