Aenon in Fausset's Bible Dictionary
Near Salim, where John baptized (John 3:22-23; John 3:26; compare John 1:28),
W. of Jordan. The name ("springs") implies" there was much water there."
Robinson found a Salim E. of Nabulus, or Shechem, with two copious springs:
compare Genesis 33:18. This would require Aenon to be far W. of Jordan; it
agrees with this that, had it been near Jordan, John would scarcely have
remarked that "much water" was there: but if far from the river, it explains
how the plentiful water at AEnon was convenient for baptisms. There is an
Ainun still near Shechem or Nabloos, with many beautiful streams and brooks.
Ainun is as distant N. of the springs (three or four miles) as Salim is S. of
them. The valley is called the wady Farah. (See SALIM.) The Ainun site is on
the main line from Jerusalem to Nazareth. Here most probably, at the upper
source of the wady Farah stream, between Salim and Ainun, was John's Aenon.
The Israel explorer, Lieut. Conder, confirms this; moreover, this would
explain John 4:4, "Jesus must needs go through Samaria; ... one soweth and
another reapeth," etc. (John 4:37-38.) John the Baptist, the forerunner,
prepared the way in Samaria; Jesus and His disciples must needs follow up by
preaching the gospel there.
