'First born' in the Bible

And she gave birth to her firstborn son, and wrapped him in strips of cloth and laid him in a manger, because there was no place for them in the inn.

because [those] whom he foreknew, he also predestined [to be] conformed to the image of his Son, so that he should be the firstborn among many brothers.

who is the image of the invisible God, the firstborn over all creation,

and he himself is the head of the body, the church, who is the beginning, the firstborn from the dead, so that he himself may become first in everything,

And again, when he brings the firstborn into the world, he says, "And let all [the] angels of God worship him."

By faith he kept the Passover and the sprinkling of blood, in order that the one who destroyed the firstborn would not touch them.

and assembly of the firstborn who are enrolled in heaven, and to God the judge of all, and to the spirits of righteous [people] made perfect,

and from Jesus Christ the faithful witness, the firstborn from the dead and the ruler of the kings of the earth. To the one who loves us and released us from our sins by his blood
