'Only begotten' in the Bible

And the Word became flesh, and dwelt among us, and we saw His glory, glory as of the only begotten from the Father, full of grace and truth.

No one has seen God at any time; the only begotten God who is in the bosom of the Father, He has explained Him.

“For God so loved the world, that He gave His only begotten Son, that whoever believes in Him shall not perish, but have eternal life.

He who believes in Him is not judged; he who does not believe has been judged already, because he has not believed in the name of the only begotten Son of God.

By faith Abraham, when he was tested, offered up Isaac, and he who had received the promises was offering up his only begotten son;

By this the love of God was manifested in us, that God has sent His only begotten Son into the world so that we might live through Him.
