'First born' in the Bible

He is the exact living image [the essential manifestation] of the unseen God [the visible representation of the invisible], the firstborn [the preeminent one, the sovereign, and the originator] of all creation.

He is also the head [the life-source and leader] of the body, the church; and He is the beginning, the firstborn from the dead, so that He Himself will occupy the first place [He will stand supreme and be preeminent] in everything.

And when He again brings the firstborn [highest-ranking Son] into the world, He says,“And all the angels of God are to worship Him.”

By faith he kept the Passover and the sprinkling of the blood [on the doorposts], so that the destroyer of the firstborn would not touch them (the firstborn of Israel).

and to the general assembly and assembly of the firstborn who are registered [as citizens] in heaven, and to God, who is Judge of all, and to the spirits of the righteous (the redeemed in heaven) who have been made perfect [bringing them to their final glory],

and from Jesus Christ, the faithful and trustworthy Witness, the Firstborn of the dead, and the Ruler of the kings of the earth. To Him who [always] loves us and who [has once for all] freed us [or washed us] from our sins by His own blood (His sacrificial death)—
