John 1:36-40

and he looked at Jesus as He walked, and *said, “Behold, the Lamb of God!”

And the two disciples heard him speak, and they followed Jesus.

And Jesus turned and saw them following, and *said to them, “What are you seeking?” They said to Him, “Rabbi (which translated means Teacher), where are You staying?”

He *said to them, “Come, and you will see.” So they came and saw where He was staying, and they stayed with Him that day; it was about the tenth hour.

One of the two who heard John speak, and followed Him, was Andrew, Simon Peter’s brother.
