John 1:23-27

He said, “I am the voice of one calling out in the wilderness, ‘Make the way of the Lord straight,’ as Isaiah the prophet said.”

And the messengers had been sent from the Pharisees.

They asked him, and said to him, “Why then are you baptizing, if you are not the Christ, nor Elijah, nor the Prophet?”

John answered them, saying, “I baptize in water, but among you stands One whom you do not know.

It is He who comes after me, of whom I am not worthy even to untie the strap of His sandal.”
