Jesus is a man now and so has a God over Him.
Heb 1:10 tells us that Ps 102:25-7 applies to Jesus, so Jesus is the God of Psalm 102:24. But that is not YHWH.
Heb 1:4 tells us that Jesus has inherited a name superior to that of the angels.
Eph 1:21 says Jesus is above every name that is named in this age and in the next. (I imagine this does not mean that He is above His own name however)
Phil 2:9 tells us that God exalted Jesus to the highest place and gave Him the name above all names. (Phil 2 is telling us that we should be humble towards those equal to us as Jesus was towards God before He became a man. He obeyed His Father and His Father exalted Him and showed everyone that He is YHWH, so that at the name of Jesus every knee would bow)
That sounds like YHWH to me. How about you?
What is interesting also is that Jesus said that everything that the Father has belongs to Him (Jesus) (John 16:15) This of course means that the name Jesus inherited (YHWH) belonged to Him even when He was alive in earth.
Before verse 15, I notice at John 16:14 it says, ' that one will glorify me ', so it is God who glorifies Jesus.
The resurrected ascended-to-heaven Jesus goes to the Father - John 16:16 B
Jesus appears in front of his God - Hebrews 9:24.
Even heavenly Jesus still thinks he has a God over him according to John at Revelation 3:12.
Before verse 10, at Hebrews 1:9 it says that God anointed Jesus. Jesus did Not anoint himself.
Thus, because the Son is the one who 'through his God' preformed his great works.
Jesus is the greater Solomon - Hebrews 1:5 B; 2 Samuel 7:14 - Not the Great or Greater God - John 17:3
I think we need to keep in mind that pre-human Jesus is part of the "us" at Genesis 1:26
So, to me it should Not surprise us that Jesus was there when earth's foundation was laid.
Pre-human Jesus acted in God's behalf - Colossians 1:15-16
Jesus gives credit to his God as Creator - Revelation 4:11
Jesus does Not commit all authority to himself but to his God - Matthew 28:18 - as Jesus represents his God.
After his God resurrected dead Jesus - Ephesians 1:20 - then Jesus became Head of the Christian congregation (KJV says ' church') and all authority would be over earth - Ephesians 1:21; Hebrews 1:4 - for salvation is through Jesus.
- Acts of the Apostles 4:12; Philippians 2:11 B - to the glory of God the Father. ( credit given to the Father )
Please notice where Jesus is located according to 1 Peter 3:22 ; Acts of the Apostles 7:55; Hebrews 10:12.
Which to me brings us back to Psalms 110.
The two (2) KJV LORD/Lords is about two (2) separate LORD/ Lords.
The Tetragrammaton LORD in ALL Capital letters YHWH.
And the some-lower-case Lord, No Tetragrammaton applied to Lord Jesus.
