And the border of the Canaanites was from Sidon, as thou comest to Gerar, unto Gaza; as thou goest, unto Sodom, and Gomorrah, and Admah, and Zeboim, even unto Lasha.
The border of the Canaanites was from Sidon, as thou comest to Gerar, unto Gaza. This was the western boundary of Canaan-the coastline. "Sidon (see the note at Genesis 10:15), as thou comest to Gerar" an idiomatic phrase used to denote the situation of one place as lying in the line of another more remote (cf. Genesis 10:30; Genesis 13:10; Genesis 25:18).
"Gaza" [Hebrew, `Azaah (H5804)] - 'the strong,' now Guzzeh, was the most southwestern city of Canaan, the last inhabited place on the confines of the desert on the southern journey from Phoenicia to Egypt. Being a border town, it was exposed to great vicissitudes during the frequent wars between the kings of the north and the south, and therefore it was, from the earliest times, a fortified place, as its name imports. "Gerar," near Beersheba (see the note at Genesis 20:1).
As thou goest, unto Sodom ... even unto Lasha. "As thou goest" - i:e., in the direction of "Lasha." This was, according to Jerome, Callirrhoe (beautiful spring), on the east of the Dead Sea, in Wady Serka Main; but far more probably, as Havernick remarks, the town (Joshua 19:47) Leshem; or (Judges 18:7; Judges 18:29) Laish, afterward called Dan, near the sources of the Jordan. The eastern boundary is here described by a line drawn from the western coast of the Dead Sea and along the course of the Jordan. All the territory included within these eastern and western limits (the southern are not defined) was 'counted to the Canaanite' (Joshua 13:3).
