(18) Thou daughter that dost inhabit Dibon.--Dibon is mentioned among the cities of Moab in Numbers 21:30; Isaiah 15:2, and as rebuilt by the Gadites in Numbers 33:45. It is prominent in the Moabite Stone inscription as a royal city. In the distribution of the conquered territory it fell to the lot of Reuben (Joshua 13:7; Joshua 13:9), but must afterwards have been retaken by Moab. The "strongholds" indicate a fortress. In Isaiah 15:9 it appears under the form of Dimon, and is there described as abounding in water, the site being probably on the north bank of the Arnon. This last feature gives point to the words of the prophet here. Its waters will not save its inhabitants from the thirst which falls on those who are dragged as captives into exile.

Verse 18. - Dibon; now Diban, one of the chief towns of Moab, on two adjacent hills, now covered with ruins (Tristram), in the plain of Medeba (Joshua 13:9), north of Aroer and the Amen. Here the famous Moabite Stone (on which see Dr. Ginsburg's exhaustive monograph), with the inscription of King Mesha (2 Kings 3:4), was found, which, after having been broke up and pieced together, has now found a resting place in the Louvre. It is difficult to say to which Israelitish tribe Dibon was, strictly speaking, attached; for while in Joshua 13:17 it is given to Reuben, in Numbers 32:34 and in the Moabite Stone (line 10) it is assigned to Gad, Apparently the Israelitish population fluctuated. Sometimes Gad was the most adventurous in Occupying Moabitish territory, sometimes Reuben. On the phrase, the daughter, etc., see note on Jeremiah 46:19. The form of the first verse haft is modelled on Isaiah 47:1. Sit in thirst. The expression is unexampled, and it is possible that we should alter one of the vowel points (which constitute no part of the Massoretic text), rendering, "sit in thirsty (ground)," i.e. the dust (comp. the parallel passage; Isaiah 47:1). Or there may be a less used collateral form of the Hebrew for "thirsty" (came). Canon Tristram speaks of the "waterless plain" of Diban ('Land of Moab,' p. 132). Thy strongholds. It appears from the Moabite Stone that Diben was the centre of a district which was reckoned as belonging to it; so at least we may account for the phrase, "all Dibon was submissive" (line 28). Compare the phrase in Numbers 21:25, "Heshbon, and all the villages thereof" (comp. on Jeremiah 49:2).

48:14-47. The destruction of Moab is further prophesied, to awaken them by national repentance and reformation to prevent the trouble, or by a personal repentance and reformation to prepare for it. In reading this long roll of threatenings, and mediating on the terror, it will be of more use to us to keep in view the power of God's anger and the terror of his judgments, and to have our hearts possessed with a holy awe of God and of his wrath, than to search into all the figures and expressions here used. Yet it is not perpetual destruction. The chapter ends with a promise of their return out of captivity in the latter days. Even with Moabites God will not contend for ever, nor be always wroth. The Jews refer it to the days of the Messiah; then the captives of the Gentiles, under the yoke of sin and Satan, shall be brought back by Divine grace, which shall make them free indeed.Thou daughter that dost inhabit Dibon,.... A city in Moab; See Gill on Isaiah 15:2. The Targum is,

"O kingdom of the congregation of Dibon;''

but this was not a kingdom of itself, though a principal city in the kingdom of Moab:

come down from thy glory, and sit in thirst; in a dry and thirsty land; in want of all the necessaries of life; in captivity; who before abounded with all good things, inhabiting a well watered and fruitful soil; see Isaiah 15:9; but now called to quit all their former glory and happiness, their fulness and felicity, and submit to the greatest straits and difficulties:

for the spoiler of Moab shall come upon thee, and he shall destroy thy strong holds; the king of Babylon and his army, who spoiled the other cities of Moab; he should come against this also, and take it, and demolish its fortifications, by reason of which it thought itself secure; but these should not be able to protect it.
