You're completely avoiding the obvious point. While Hebrews 1:10-12 is quoting Psalms 102:25-27, the reason it is being quoted is important. And that reason is given in Hebrews 1:8--it is God, the Father, speaking "in reference to the Son" or, as the NWT Study Edition puts it, "But about the Son, he says." In other words, God is saying that it is the Son being spoken of as the Creator. It is God applying the name Jehovah to the Son.Hebrews is a quote of Psalm, so it is speaking of Jehovah in both spots. Because as you can see verse 8 clearly shows Jesus has a God and he has partners( Angels)- verse10 is Jehovah.
There is no getting around it. Just one more contradiction between what the Watchtower teaches and what their own translation teaches.
What are your thoughts on Romans 10:9-13?
‘9 For if you publicly declare with your mouth that Jesus is Lord, and exercise faith in your heart that God raised him up from the dead, you will be saved. 10 For with the heart one exercises faith for righteousness, but with the mouth one makes public declaration for salvation.
11 For the scripture says: “No one who rests his faith on him will be disappointed.” 12 For there is no distinction between Jew and Greek. There is the same Lord over all, who is rich toward all those calling on him. 13 For “everyone who calls on the name of Jehovah will be saved.”’ (NWT)
This one is a bit tricky, but if you do a bit of study, you will find that it, too, is applying an OT passage about Jehovah to Jesus. That is, to call on the name of Jesus is to call on the name of Jehovah.
