These things happened in Bethany on the east side of the Jordan River where John was immersing people. [Note: This was a different Bethany from the one just outside of Jerusalem].
John [the Immerser] was also immersing people in Aenon, near Salem [Note: These locations are thought to have been in northeastern Judea, near the Jordan River], because there was a lot of water there; so people were coming to be immersed.
These disciples went to John and said to him, “Rabbi, look, that man who was with you on the east side of the Jordan River [i.e., Jesus], whom you testified about, is immersing people and everyone is going to him.” [Note: Actually, it was Jesus’ disciples who did the immersing. See 4:2].
“Why was this perfume not sold for a large sum of money [Note: The amount here was equivalent to three hundred twelve-hour days of a farm laborer’s pay, or over $32,000 in 2005] and [then] the money given to poor people?”
[Then] on the next day He [i.e., Jesus, but some think it refers to Peter or Andrew] decided to travel into Galilee, [and there] He found Philip. Jesus said to Philip, “Become my follower.”
