John 1:25-29

And they asked him, and said unto him, Why baptizest thou then, if thou be not that Christ, nor Elias, neither that prophet?

John answered them, saying, I baptize with water: but there standeth one among you, whom ye know not;

He it is, who coming after me is preferred before me, whose shoe’s latchet I am not worthy to unloose.

These things were done in Bethabara beyond Jordan, where John was baptizing.

The next day John seeth Jesus coming unto him, and saith, Behold the Lamb of God, which taketh away the sin of the world.
