How Seleucia Pieria: Harbour of Antioch and the Titus Tunnel was found
The rock-cut channel above the silted harbour bears carved inscriptions naming Vespasian and Titus at one entrance and Antoninus at the discharge end; the Princeton team dug in the upper city while studying the harbour moles.
What it is
A walled port city on the slope above the Orontes mouth, with the remains of two harbour basins, a Doric temple, a market gate and the Beşikli rock-cut tombs. The Titus Tunnel is a 1,380 m flood-diversion system — dam, open channel and two tunnel sections up to 7 m high — cut through solid rock by hand, reportedly by Jewish prisoners of the war of 70 CE, to stop the mountain torrent silting the harbour.
Why it matters for the Bible
Acts 13:4 says Barnabas and Saul 'went down to Seleucia and from there sailed to Cyprus' — this is the harbour. The great tunnel was begun by the same Vespasian and Titus who destroyed Jerusalem, and Josephus and later sources say captives from that war laboured on Roman works; an inscription here in Latin names both emperors. Harbour and tunnel together show the Roman engineering that carried the gospel by sea and the empire's power over Judea in the same generation.
The Hebrew word: mah-CHOHZ
מָחוֹז
מָחוֹז is pronounced mah-CHOHZ and means haven, harbour — 'he brought them to their desired haven' (Psalm 107:30) (Strong's H4231).
