E herdaram todo o território dos Emoritas, desde o Arnon até o Jaboque, e desde o deserto até o Jordão.

ממדבר קדמות, “from the desert of Kedemot.” The name of that desert is related to the well known expression קדמה מזרחה, “forward in an easterly direction.” In other words, the desert took its name from the fact that it was situated in the east, as opposed to the south, where most of the deserts in the region were located. Compare Judges 11,22: ויירשו את כל גבול האמורי מארנון עד היבוק ומן המדבר עד הירדן, “and they appropriated (as an inheritance) all the territory of the Ammonites from the Arnon river to the Yabbok river and from the wilderness to the Jordan.”
