“A remarkable indicator of the high christology of the New Testament writers can be seen in the rather comfortable way in which they are able to understand Jesus as the YHWH of certain Old Testament texts. Obviously this shows that writers of the New Testament thought of Jesus as the manifestation of deity. Thus, he could be equated with YHWH.
Some of the most important New Testament texts in which Jesus is understood as YHWH are Acts 2:21, 2:34-35; Romans 10:13; Philippians 2:9-11; 1 Peter 3:15-16 (Isa. 8:13); Revelation 19:16.” -Donald Hagner, Encountering the Book of Hebrews
