Lasha
Lasha appears once, as the eastern endpoint of a boundary line drawn around early Canaan in the Table of Nations.
A boundary marker of Canaan
Genesis 10:19 traces the territory of the Canaanite clans: "And the border of the Canaanite was from Sidon, as you go toward Gerar, to Gaza; as you go toward Sodom and Gomorrah and Admah and Zeboiim, to Lasha."
The line runs from Sidon on the north coast down through Gerar to Gaza in the southwest, then eastward across the cities of the plain and out to Lasha. Lasha closes the perimeter on the southeastern side, completing the framing of Canaanite territory in the genealogical map.
