John 1:24-28

Now the Pharisees who had been sent questioned him, “Why then do you baptize if you are not the Messiah, nor Elijah, nor the Prophet?” “I baptize with water,” John replied, “but among you stands one you do not know. He is the one who comes after me, the straps of whose sandals I am not worthy to untie.” This all happened at Bethany on the other side of the Jordan, where John was baptizing.
