Hastings' Dictionary of the Bible
ZEMARITE, THE . A collective designation of one of the Canaanite communities in Genesis 10:18 , named along with the Arvadite, and therefore presumably in Northern PhÅnicia. It stands probably for the people of Simirra , an important city in the time of the later Assyrian empire and the seat of an Assyrian province. It seems to be mentioned also in the Amarna letters under the name Sumur . Perhaps we should compare the modern Sumra , between RuwÃ¢d (Arvad) and TarabulÃ»s (Tripolis).

The designation of one of the Phoenician tribes (Genesis 10:18 ) who inhabited the town of Sumra, at the western base of the Lebanon range. In the Amarna tablets (B.C. 1400) Zemar, or Zumur, was one of the most important of the Phoenician cities, but it afterwards almost disappears from history.
