John 1:6-8, 15

There came a man, sent from God, whose name was John. The same came for witness, that he might bear witness of the light, that all might believe through him. He was not the light, but came that he might bear witness of the light.

John beareth witness of him, and crieth, saying, This was he of whom I said, He that cometh after me is become before me: for he was before me.
