You quote Acts 2:32–36 presumably from the NWT
God resurrected this Jesus, and of this we are all witnesses. Therefore, because he was exalted to the right hand of God and received the promised holy spirit from the Father, he has poured out what you see and hear. For David did not ascend to the heavens, but he himself says, ‘Jehovah said to my Lord: “Sit at my right hand until I place your enemies as a stool for your feet.”’ Therefore, let all the house of Israel know for a certainty that God made him both Lord and Christ, this Jesus whom you executed on a stake.”
JWs feel free to substitute the doubtful name "Jehovah" in the NT where the unpronounceable Tetragrammaton is found in OT passages. In fact they add the name "Jehovah" 327 times to the NT...when the majority of these self serving additions are not even based on OT quotations.
Unfortunately however, as William Cetnar demonstrated, the WT has failed to be consistent in its application of the divine name to NT passages that include quotations from the OT.
For example consistency would yield the following
1 Peter 3:15 quoted from Isaiah. 8:12 - But sanctify the Christ as Jehovah in your hearts.
Phil 2:10-11 quoted from Isaiah 45:23 - "...so that in the name of Jesus every knee should bend... and every tongue should openly acknowledge that Jesus Christ is Jehovah to the glory of God the Father."
1 Peter 2:3 quoted from Psalm 34:8 - "...provided you have tasted that Jehovah is kind. Coming to him as to a living stone, rejected, it is true, by men, but chosen, precious, with God,"
Hebrews 1:10 quoted from Psalms 102:25 - "And: "You at the beginning, O Jehovah, laid the foundation of the earth itself."
Let's review: The doubtful name "Jehovah" is not found once in the OT, nor once in the NT, nor is the Tetragrammaton found once in the NT. And over half the 327 times the NWT imposes the name "Jehovah" on NT passages, no precedent is provided from the OT. It is never found on the lips of Jesus, or the disciples or the apostle Paul. The name is hidden throughout the Bible. Christians are told to address God as "Father" for that is the intimate relationship He desires for all His children. Jesus, like His Father, did not make the name "Jehovah" known to anyone. Rather He made God's person, nature and attributes known to His followers by both word and action.
