Numbers 21:20

the valley that is in the region of Moab, [om. to the top of the Pisgah The two expressions are placed somewhat awkwardly in apposition; but they appear to mean: the valley which is in that part of the region of Moab known as the top of the Pisgah.

the valley was a glen (gay", distinct from naḥal, Numbers 21:14) which cut through the hills and emerged at the Jordan, perhaps the present Wâdy -Ayûn Mûsa(-Moses" springs") which runs into the Jordan valley some four or five miles north of the northern end of the Dead Sea, the torrent then flowing with a south-westerly curve into the Sea.

the region of Moab denotes the region which properly belonged to Moab, but of which the Amorites were in possession at the moment.

the top of the Pisgah -The Pisgah" seems to have been the name applied to the broken edge of the Moabite plateau where it falls steeply to the Dead Sea and the Jordan valley; and -the top, or head, of the Pisgah" (Numbers 23:14; Deuteronomy 3:27; Deuteronomy 34:1) is a collective term for the projections or promontories slightly lower than the main plateau and standing out from the western slopes. The word is derived from a root which in Aram. and late Heb. signifies -to cleave"; and it may describe the appearance of the range as seen from the west, standing out in a series of separate peaks.

which looketh down upon the Jeshimon] The name, which denotes -arid or desert land," is used of the deserts through which Israel passed in their journey from Egypt (Deuteronomy 32:10; Psalms 68:7 &c.), and of the waste land on the east of Judah, north of the Dead Sea (1 Samuel 23:19; 1 Samuel 23:24; 1 Samuel 26:1; 1 Samuel 26:3 marg.). But here the verb -looketh down," which is chiefly used of men looking down from a window (Genesis 26:8; 2 Samuel 24:20; Song of Solomon 6:10), or of God looking down out of heaven (Psalms 102:19), seems to point to a district more immediately below the Pisgah, which must be the barren tract north of the Dead Sea and eastof the Jordan (see G. A. Smith, H. G.[Note:. G. Historical Geography of the Holy Land.] 564 note).
