Deuteronomy 2:19

19.And when thou comest nigh over against the children ofAmmon. God now makes provision as to the Ammonites, since their condition was the same as that of the Moabites, inasmuch as they were descended from the two daughters of Lot. It might, indeed, seem wonderful that, since the memory of their origin was detestable, these two nations should have been so dear to God. Ammon and Moab had been born of an incestuous connection. It was, therefore, more reasonable that this tragical circumstance should have been buried by their destruction, than that they should have been distinguished by God’s favor from the common lot of other nations, as if their nobility rendered them superior to others. But let us learn from hence, that since God’s judgments, like a deep abyss, are beyond our apprehension, they should be regarded with reverence. Lot’s distinguished piety is expressly declared. The disgraceful crime, which he committed when drunk, it pleased God so to mark with perpetual infamy, as still to impress upon it some signs of His mercy, although this was done especially for the sake of Abraham himself. It is unquestionable, however, that God recommends the posterity of Lot to the Israelites on this ground, that they may more willingly exercise kindness towards them, and abstain from all injury, when they had to do with two nations whom they see to be cared for by God Himself, for the sake of their common relationship to Abraham.

Furthermore, by the same argument whereby he had before proved that both Edomites and Moabites, relying on God’s help, had occupied the lands over which they had dominion, he now establishes that the land which the Ammonites possessed had been granted them by God, viz., because in their conquest and overthrow of the giants they had surpassed the limits of human bravery, and thus God had given a proof of His special and unusual favor towards them. For neither by the ordinary course of nature could two men increase to so great a multitude.

Now, although the Hebrew call the Cappadocians Caphthorim, (127) we do not know whether the giants, whose country was taken possession of by the Ammonites, sprung from them. But, if this be admitted, they had a long journey, attended by many dangers, after they left their country; and again, since they must have passed through rich and fertile regions, it is strange that they should have penetrated to those mountains. It might, however, be the case, that, making forays as robbers, they nowhere found a quiet resting-place until a less cultivated region presented itself.
