Исаия 15:7

As Moabitis has thus become a great scene of conflagration, the Moabites cross the border and fly to Idumaea. The reason for this is given in sentences which the prophet again links on to one another with the particle ci (for). "Therefore what has been spared, what has been gained, and their provision, they carry it over the willow-brook. For the scream has gone the round in the territory of Moab; the wailing of Joab resounds to Eglayim, and his wailing to Beeer-Elim. For the waters of Dimon are full of blood: for I suspend over Dimon a new calamity, over the escaped of Moab a lion, and over the remnant of the land." Yithrâh is what is superfluous or exceeds the present need, and pekuddâh (lit. a laying up, depositio) that which has been carefully stored; whilst ‛âsâh, as the derivative passage, Jer 48:36, clearly shows (although the accusative in the whole of Isa 15:7 is founded upon a different view: see Rashi), is an attributive clause (what has been made, worked out, or gained). All these things they carry across nachal hâ‛arâbim, i.e., not the desert-stream, as Hitzig, Maurer, Ewald, and Knobel suppose, since the plural of ‛arâbâh is ‛arâboth, but either the Arab stream (lxx, Saad.), or the willow-stream, torrens salicum (Vulg.). The latter is more suitable to the connection; and among the rivers which flow to the south of the Arnon from the mountains of the Moabitish highlands down to the Dead Sea, there is one which is called Wadi Sufsaf, i.e., willow-brook (Tzaphtzphh is the name of a brook in Hebrew also), viz., the northern arm of the Seil el-Kerek. This is what we suppose to be intended here, and not the Wadi el-Ahsa, although the latter (probably the biblical Zered (Note: Hence the Targ. II renders nachal zered "the brook of the willows." See Buxtor…

This chapter, and that which follows it, are the burden of Moab - a prophecy of some great desolation that was coming upon that country, which bordered upon this land of Israel, and had often been injurious and vexatious to it, though the Moabites were descended from Lot, Abraham's kinsman and companion, and though the Israelites, by the appointment of God, had spared them when they might both easily and justly have cut them off with their neighbours. In this chapter we have, I. Great lamentation made by the Moabites, and by the prophet himself for them (Isa 15:1-5). II. The great calamities which should occasion that lamentation and justify it (Isa 15:6-9).

15:7-8 The precise locations of the Ravine of Willows and of Eglaim and Beer-elim are uncertain.
