If firstborn always means the first born why was the word applied to David when he was the last born son? It is clear the context shows that the term was referring to David’s position of preeminence.
It is the Watchtower’s NWT which has inserted words and altered the Bible to fit their particular antichrist slant. The insertion of the word OTHER is one example. There are others, including the addition of “a” in John 1:1 in an attempt to turn Jesus into “a god” instead of God.
“Because by means of him all
[other] things were created in the heavens and upon the earth, the things visible and the things invisible, no matter whether they are thrones or lordships or governments or authorities. All
[other] things have been created through him and for him. Also, he is before all
[other] things and by means of him all
[other] things were made to exist.” Colossians 1:16-17 – NWT
The word “OTHER” does not appear AT ALL in either of these two verses in the original Greek manuscripts, as attested to by the correct translation of these verses in the King James version:
For by him were all things created, that are in heaven, and that are in earth, visible and invisible, whether they be thrones, or dominions, or principalities, or powers: all things were created by him, and for him: And he is before all things, and by him all things consist.” Colossians 1:16-17 – KJV“

The Catholic Church has deviated extremely from the scriptures, but it did not invent the Trinity. The triune nature of God is revealed throughout the scriptures, as it is stamped upon God’s creation.
“The Bible presents a God who did not need to create any beings to experience love, communion and fellowship. This God is complete in Himself, being three Persons: Father, Son and Holy Spirit, separate and distinct, yet at the same time eternally one God. They loved and communed and fellowshiped with each other and took counsel together before the universe, angels or man were brought into existence. Isaiah "heard the voice of the Lord [in eternity past] saying, "Whom shall
I send, and who will go for
us?" (Isa:6:8). Moses revealed the same counseling together of the Godhead: "And God said, Let
us make man in
ourimage, after
our likeness"; and again, "Let
us go down, and there confound their language" (Gen:1:26
;11:7). Who is this "us" if God is a single entity? Why does God say, "The man is become as one of
us" (Gen:3:22)?
Moreover, if God is a single Being, then why is the plural Hebrew noun
elohim(literally "gods") used for God repeatedly?
“In Romans:1:20 Paul argues that God's "eternal power and Godhead" are seen in the creation He made. God's eternal power—but His
Godhead? Yes, as Dr. Wood pointed out years ago in
The Secret of the Universe, the triune nature of God is stamped on His creation. The cosmos is divided into three: space, matter and time. Each of these is divided into three. Space, for instance, is composed of length, breadth and width, each separate and distinct in itself, yet the three are one. Length, breadth and width are not three spaces, but three dimensions comprising one space. Run enough lines lengthwise and you take in the whole. But so it is with the width and height. Each is separate and distinct, yet each is all of space—just as the Father, Son and Holy Spirit is each God.
Time also is a trinity: past, present and future—two invisible and one visible. Each is separate and distinct, yet each is the whole. Man himself is a triunity of spirit, soul and body, two of which are invisible, one visible. Many more details could be given of the Godhead's triunity reflected in the universe. It can hardly be coincidence.”
