Albert Barnes Commentary Joshua 19:46

"and Me-jarkon, and Rakkon, with the border over against Joppa." — Joshua 19:46 (ASV)

Japho (the modern Jaffa, or Yafa), elsewhere (according to the margin) called Joppa, is often mentioned in the history of the Maccabees and was, as it still is, the leading port of access to Jerusalem both for pilgrims and for merchandise. It is a very ancient town.
