Ptolemais in the New Testament, Jean d'Acre (named from the knights of John of Jerusalem); called "the key of Palestine." Its sands were employed by the Sidonians in making glass. The name is akin to the Arab Akeh, a sandy shore heated by the sun. The chief seaport in Syria, 30 miles S. of Tyre; on the N. of the only inlet on the Palestine coast, with Carmel on the S. side. The distance across is eight miles. The river Belus flows into the sea close under the town walls. Accho was Asher's portion, but never was wrested from the original dwellers (Judges 1:31). Paul landed here from Tyre, and stayed one day with Christian brethren, before sailing on to Caesarea (Acts 21:7).
