These things were done in Bethabara beyond Jordan, where John was baptizing.
Jhn 1:29¶The next day John seeth Jesus coming unto him, and saith, Behold the Lamb of God, which taketh away the sin of the world.
Jhn 1:30This is He of Whom I said, After me cometh a Man which is preferred before me: for He was before Me.
Jhn 1:31And I knew Him not: but that He should be made manifest to Israel, therefore am I come baptizing with water.
John had been baptizing in the Jordan near Bethabara (Bethany) “beyond” (on the other side of) the Jordan River. I would love to see that spot and visualize the drama of the moment when John baptized Jesus Christ!
On the day following John’s interview with the priests and Levites, he looked up and saw Jesus! That in itself is an earth-shaking, profound moment!
His response was immediate and dynamic: “Behold the Lamb of God, which taketh away the sin of the world!”
John clearly understood Who Jesus was, what He had come to do, and what his own job was in preparing the way for Jesus. There was a great humility in him, as well as a great boldness.
He goes on to repeat what he had told the priests and Levites: “Jesus will come after me, but He was (existed) before me. I didn’t know Him, but I knew Who He would be! He is the salvation of Israel. That’s why I am preparing the way for Him, by water baptism, which symbolizes the desire of those who are willing to hear the Word of God.”
