Hi DJW
This thread is not particularly about the Trinity, but there does seem to be considerable evidence that Jesus is Jehovah when comparing OT passages with passages in the NT.
Randal Waters cites a few.
[1] Hebrews 1:10 is a quotation of the LXX version of Ps. 102:25. The Psalm is unquestionably speaking of Jehovah, yet the writer of Hebrews applies it to Christ! Knowing this, the New World Translating Committee broke their own rules and refused to insert "Jehovah" into Hebrews 1:10. *2
[2] 1 Peter 3:14,15 is a quote from Isa. 8:12,13, which obviously contained the tetragram in the Hebrew text and referred to "sanctifying Jehovah in our hearts." Yet, Peter paraphrases it and applies it directly to Christ, saying that we are to sanctify CHRIST in our hearts! Again, their Translating Committee has shown bias in not following their own rules. Even the footnote in the Kingdom Interlinear shows that many of the modern Hebrew Bibles have "Jehovah" in 1 Peter 3:15. But since that would identify Christ with Jehovah, the Translating Committee could not face up to it.
[3] Acts 2:21 quotes from a prophecy in Joel 2:2832 that contained the tetragram in the Hebrew text, saying, "Whoever calls upon the name of Jehovah will be delivered." Yet Peter quotes it and applies it to Jesus in Acts 2:21, as verse 38 says, "And Peter said to them, `Repent, and let each of you be baptized in the name of Jesus Christ for the forgiveness of your sins; and you shall receive the gift of the Holy Spirit.'"
Additionally, the name of Jesus takes great precedence over "Jehovah" in the New Testament. Just in the book of Acts alone, note the overwhelming importance of the name of Christ, with no mention of the covenant name of God:
Men healed in the Name | Acts 3:6,16; 4:10,30 |
Salvation in the Name | Acts 4:12; 10:43; 22:16 |
Baptism in the Name | Acts 2:38; 8:16 |
Forgiveness through the Name | Acts 10:43 |
Teaching and preaching in the Name | Acts 8:12; 4:18; 5:28 |
Calling upon the Name | Acts 2:21; 9:14,21 |
Speaking in the Name | Acts 4:17; 9:27,29 |
Suffering for the name | Acts 9:16; 15:26; 5:41 |
Bearing the Name before the nations | Acts 9:15 |
Paul once opposed the Name | Acts 26:9 |
Called or designated by the Name | Acts 11:26 |
The New Testament record shows that the Name of Jesus holds primary importance, rather than the covenant Name of Jehovah. This is in line with Hebrews 1:1,2 where it is said that God, though speaking through his covenant people in times past, is now speaking through the Son; who is the exact representation of the Father (but not the Father). Note also other NT texts that speak of the Name of Jesus as being the most important name there is: Eph. 1:20,21; Phil. 2:9; 2 Thess. 1:12; 1 Cor. 1:2; Col. 3:17; 1 John 3:23; Rev. 2:3, 13. Jesus also spoke of the importance of his name in passages such as: Mt. 7:22; 10:22; 12:1521; 18:5,20; 19:29; 24:9; 28:19,20 (just to cite Matthew).
