John 1:23-28 NASB
He said, “I am A VOICE OF ONE CRYING IN THE WILDERNESS, ‘MAKE STRAIGHT THE WAY OF THE LORD’ as Isaiah the prophet said.”
Now they 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 baptise in water, but among you stands One whom you worthy to untie.”
“It is He who comes after me, the thong of whose sandal I am not worthy to untie.”
These things took place in Bethany beyond the Jordan, where John was baptizing.
