Hi Sea Breeze that is a good example you gave from Philippians which supports the point I made, but I think you meant 2:9 instead of 1:9. By the way, I also notice that in the 1984 NWT the brackets are in Philippians 2:9, but in that verse the brackets were not in any prior edition of the NWT. I'm guessing that the WT had added them to the 1984 revision of that verse due to criticisms by evangelicals and/or non-JW scholars of the Bible.
Your drawing attention to Philippians 2:9 reminds of something I have noticed about the NT which is very puzzling to me. The name Jesus (Iesous in Greek; Yeshua in Hebrew) was a very common Jewish name during the time that Jesus Christ lived on Earth (if he ever was a historical person) and is simply a variation of the name Yoshua/Joshua (which in turn is a contracted form of the name Yehoshua), which was also a very common Jewish name. It is thus very puzzling to me that the NT makes a big deal about that name Jesus being special when applied to Christ, when the one called Christ (if he ever existed) was by no means the first human to have that name. [For other examples of the NT making a big deal about the name Jesus, see Matthew 1:21 and Luke 1:31-33.]
During most of my active time as a JW I didn't know that the name Jesus was very common in the early 1 century CE, and probably most Christians today also don't realize it was very common. Luke 3:29 even lists a person named Jesus as an ancestor of Jesus Christ! For some documentation of that see the 1984 NWT and the Bible translated by Goodspeed and Smith (though the name Joshua or Jose is used in many other Bible translations). Even the criminal Barabbas (the one who the NT says Pilate released instead of Jesus Christ), according to some NT manuscripts of Matthew 27:16–17 (see the NRSV, the translators' note in the RSV, TNIV, REB, and the 1991 NAB) was named Jesus Barabbas (meaning Jesus son of the father)! The crowds thus were asked which Jesus they wanted to be released, namely "Jesus Barabbas or Jesus who is called the Messiah" (NRSV)!
[ https://en.wikipedia.org/wiki/Barabbas says the following. "These versions, featuring the first name "Jesus" are considered original by a number of modern scholars.[12][13] The Church Father Origen
seems to refer to this passage of Matthew in claiming that it must be a
corruption, as no sinful man ever bore the name "Jesus" and argues for
its exclusion from the text.[14] He however does not account for the high priest Biblical Greek: Ἰάσων, romanized: Iásōn from 2 Maccabees
4:13, whose name seems to transliterate the same Aramaic name into
Greek, as well as other bearers of the name Jesus mentioned by Josephus.[10]
It is however also possible that later scribes, when copying the
passage, removed the name "Jesus" from "Jesus Barabbas" to avoid
dishonor to the name of Jesus whom they considered the Messiah.[15] ]
Furthermore, the name Jesus/Joshua/Yeshua honors the name Jehovah/Yahweh/Yah/YHWH since it literally means "Jehovah/Yahweh/Yah/YHWH saves" or "Jehovah/Yahweh/Yah/YHWH is salvation", though some sources (incorrectly in my view) say it means "salvation" or "savior". For example, note that https://aleteia.org/2019/05/13/what-is-the-meaning-of-the-name-jesus/ says the following.
'The Catholic Encyclopedia points out that the Hebrew name Jeshua—or Joshua, or Jehoshua—means “Jehovah is salvation.” The Greeks transliterated that as Iesous, which in turn gave us the Latin form, Jesus.
“Though
the name in one form or another occurs frequently in the Old Testament,
it was not borne by a person of prominence between the time of Josue,
the son of Nun and Josue, the high priest in the days of Zorobabel,” the
Catholic Encyclopedia notes. “It was also the name of the author of
Ecclesiasticus, of one of Christ’s ancestors mentioned in the genealogy,
found in the Third Gospel (Luke 3:29), and one of St. Paul’s companions
(Colossians 4:11).' Admittedly that Catholic source goes on to say the following. 'Though about the time of Christ the name Jesus appears to have been
fairly common … it was imposed on our Lord by God’s express order (Luke
1:31; Matthew 1:21), to foreshow that the Child was destined to ‘save
his people from their sins.'” '
