And they asked him, and said unto him, Why baptize you then, if you are not that Christ, nor Elijah, neither that prophet? John answered them, saying, I baptize with water: but there stands one among you, whom you know not; He it is, who coming after me is preferred before me, whose shoe's thong I am not worthy to unloose. These things were done in Bethany beyond Jordan, where John was baptizing. (John 1:25-28)
