'Only begotten' in the Bible

And the Word became flesh, and dwelt among us, full of grace and truth; and we beheld his glory, a glory as of an only begotten of a father.

No one hath ever seen God; the only begotten God, who is in the bosom of the Father, he hath made him known.

For God so loved the world, that he gave the only begotten Son, that every one who believeth in him may not perish, but may have everlasting life.

He that believeth in him is not condemned; he that believeth not hath already been condemned, because he hath not believed in the name of the only begotten Son of God.

By faith Abraham, when tried, offered up Isaac, and he who had received the promises was offering up his onlybegotten son,

In this was manifested the love of God in regard to us, that God hath sent his only begotten Son into the world, that we may live through him.
