From the wilderness and this Lebanon. The wilderness refers to the wilderness of Kodeish, the wilderness of Tzin, which was adjacient to Edom which was to the south east, the direction from which they entered the land, as it is said: And behold we are in Kodeish.11Bamidbar 20:16. How do we know that it was southeast? It is said: ‘Your southern flank will be from the Tzin wilderness along Edom.’12Bamidbar 34:3.
