'Only begotten' in the Bible

And the Word became flesh, and dwelt among us (and we have contemplated his glory, a glory as of an only-begotten with a father), full of grace and truth;

No one has seen God at any time; the only-begotten Son, who is in the bosom of the Father, he hath declared him.

For God so loved the world, that he gave his only-begotten Son, that whosoever believes on him may not perish, but have life eternal.

He that believes on him is not judged: but he that believes not has been already judged, because he has not believed on the name of the only-begotten Son of God.
