And Israel took all these cities. As if speaking of something present, he uses the demonstrative pronoun, and says, |these cities,| just as if he were pointing them out to the eyes of his readers. The word which we have rendered |towns| (oppida,) others translate |country-houses| (villas,) or |hamlets| (viculos.) In the Hebrew, Moses calls by the name of |daughters| all the villages and lesser towns, whose mother-city (metropolis) was Heshbon. By these words, however, Moses indicates that, by the right of war, all these places had fallen into the hands of the Israelites, as the lot of their inheritance; for, as I have lately said, God had not yet openly declared that they should be masters of this part of the country. They would consequently have over-passed their boundaries, unless these had been added to the land of Canaan. This is the reason why God openly declares that they possessed them by His authority. But when he says that the cities were destroyed, and all their inhabitants exterminated, so that neither women nor children were spared, let us understand that they dealt not thus cruelly of their own impulse, or in heedless violence, but that whatsoever was on the other side of Jordan was devoted to destruction by God, that they might always have their minds fixed on the promised land, and might never give way to listlessness, which would have been the case if an easy occupation of it had invited them to repose. Although, therefore, God delivered over the land to them hereafter, and suffered them to enrich themselves with its booty and spoils, yet He would not have it retained as a place of residence, and therefore commanded them to destroy its cities and villages, in order that they might seek their rest elsewhere. In fine, since they were abundantly disposed to be slothful, it was expedient that all snares should be removed, and that by the very desolation they might be urged forward whither God called them.
26. For Heshbon was the city of Sihon. It is not without cause that Moses relates how the country near Heshbon had passed into the hands of the Amorites, because a long time afterwards this was sought for as a pretext for war by the Ammonites, when they saw that the people were brought into a low estate. In the time of Jephthah, therefore, having collected a great army, an irruption was made by them; and they made this their excuse, that they took up arms to recover what was their own, from Arnon as far as Jabbok, and as far as Jordan. Consequently, God would have it testified in the sacred records, as Jephthah then replied to the Ammonites, that this part of the land was taken from king Sihon, when the children of Israel were marching peacefully through the borders of the Ammonites. Designedly, then, did Moses, in order to sanction the right of the people, insert in these authentic registers, as it were, what had formerly occurred, namely, that the Amorites had had the dominion over that part of the country, without interference from the Ammonites; nor was there any question that the Amorites had secure and peaceful possession of it. Hence it follows that it passed to the Israelites, so that there were no grounds why, three hundred years afterwards, the Ammonites should reclaim what had so long been lost and abandoned by them. And, in order that posterity might know that there was then no obscurity about the matter, he records an ancient canticle, from which it appears that the Ammonites were so completely overcome, that their enemies triumphed magnificently over them, and cut off all hope of their restoration. Here, however, the question arises, why the king of Ammon, rather than the king of Moab, set on foot that war; for we clearly gather from the song, that the land was taken from the Moabites. But for men who are bent on rapine and robbery, it is sufficient to allege any trivial pretext, and often to glory in the rights of others. There doubtless remained a report that the Amorites had been driven out of their territories, which they had obtained by force of arms. The Ammonites pass over in silence what had been forgotten in the lapse of many ages, and set up this false title, that, although the Israelites had conquered the Amorites, still their victory conferred upon them no right to occupy what the Amorites unjustly and forcibly held. With this object Moses inserted the account he here gives.
27. Wherefore, they that speak in proverbs. That is, an old saying, or proverbial sentence remains, and is well known. The song, however, appears to have been composed in the character of those who, when prepared to engage in war, mutually exhorted each other, |Come into Heshbon,| i.e., run to the standard of king Sihon; hasten to his home, and his chief place of abode, in order that we may thence go forth to battle. These expressions, |build and prepare,| I interpret as being used for enlarge, adorn, and enrich; for it is probable that this city was not overthrown, but they foretell that the city would be renovated, when a larger dominion had been gained. And this is more fully confirmed by what immediately follows, when it is said that |a fire had gone forth from Heshbon,| which consumed Ar of Moab, and all its neighborhood. As to the |lords of the high places of Arnon,| some understand the priests who presided in the temples; others extend them to all the inhabitants in general; but, in my opinion, it will not be unsuitable to refer them to the idols themselves, since it appears from the next verse that the conquerors were so insolently elated, as not only to despise the men themselves, but their gods also; for when they say, |Thou art undone, O people of Chemosh,| there is no doubt but that they mockingly reproach them with the fact that they had been badly defended by the gods whom they worshipped. And, in point of fact, ungodly men, when in prosperity, uplift their horns to heaven, as if they would assail the divinity which was opposed to them. They, therefore, deride Chemosh, because he made |his sons| or worshippers to be fugitives or captives.
In the word lantern he makes use of a common metaphor. Some follow the Chaldee interpreter, and render it kingdom; but it has a wider signification; for it includes all the component parts of a happy and prosperous state. The meaning, therefore, is, that their glory and all their wealth was annihilated. The cities of Dibon and Medeba are situated on the extreme borders, near the river Arnon, so that by these he designates all the intermediate plain.
