Tel Aviv is Israel's largest city and it's located next to the Mediterranean Sea. Various people have asked on the Internet if Tel Aviv is found in the Bible. (Example: Yahoo Answers)
The name Tel Aviv does appear in the NIV and World English Bible translations of Ezekiel 3:15. However, most English Bible versions use the name Tel-Abib in this verse. The King James Version uses the name Telabib (no hyphen).
Ezekiel 3:15 in the New Living Translation:
Then I came to the colony of Judean exiles in Tel-abib, beside the Kebar River. I was overwhelmed and sat among them for seven days.
According to Wikipedia, the town in Ezekial 3:15 "is an unidentified place on the river Khabur in what is now Syria."
Tel Aviv is a recent name for this city. It was previously known as Jaffa.
Jaffa is mentioned several times in the Bible, as the port from which Jonah set sail for Tarshish; as bordering on the territory of the Tribe of Dan; and as the Jaffa Port at which the wood for Solomon's Temple in Jerusalem arrived from Lebanon. Jaffa is also mentioned as the place where the Apostle Peter raised Tabitha and visited Simon the Tanner.
