'First born' in the Bible

as it is written in the Law of the Lord, "Every firstborn son is to be designated as holy to the Lord."

For those whom he foreknew he also predestined to be conformed to the image of his Son, in order that the Son might be the firstborn among many brothers.

The Son is the image of the invisible God, the firstborn over all creation.

He is also the head of the body, which is the church. He is the beginning, the firstborn from the dead, so that he himself might have first place in everything.

And again, when he brings his firstborn into the world, he says, "Let all God's angels worship him."

By faith he established the Passover and the sprinkling of blood to keep the destroyer of the firstborn from touching the people.

to the assembly of the firstborn who are enrolled in heaven, to a judge who is the God of all, to the spirits of righteous people who have been made perfect,

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