Verse 38. - And the younger, she also bare a son, and called his name Ben-ammi. I.e. son of my people (LXX., Jerome, Augustine), meaning that her child was the offspring of her own kind and blood (Rosenmüller), or the son of her relative (Kalisch), or of an unmixed race ('Speaker's Commentary'). The same is the father of the children of Ammon - an unsettled people who occupied the territory between the Yabbok and the Arnon, from which they had ejected the Rephaims or Zamzummims (Deuteronomy 2:22), and in which they possessed a strong city, Rabbah (2 Samuel 40:1); in their habits more migratory and marauding than the Moabites (Isaiah 15, 16; Jeremiah 48.), and in their religion worshippers of Molech, "the abomination of the Ammonites" (1 Kings 11:7) - unto this day.

19:30-38 See the peril of security. Lot, who kept chaste in Sodom, and was a mourner for the wickedness of the place, and a witness against it, when in the mountain, alone, and, as he thought, out of the way of temptation, is shamefully overtaken. Let him that thinks he stands high, and stands firm, take heed lest he fall. See the peril of drunkenness; it is not only a great sin itself, but lets in many sins, which bring a lasting wound and dishonour. Many a man does that, when he is drunk, which, when he is sober, he could not think of without horror. See also the peril of temptation, even from relations and friends, whom we love and esteem, and expect kindness from. We must dread a snare, wherever we are, and be always upon our guard. No excuse can be made for the daughters, nor for Lot. Scarcely any account can be given of the affair but this, The heart is deceitful above all things, and desperately wicked: who can know it? From the silence of the Scripture concerning Lot henceforward, learn that drunkenness, as it makes men forgetful, so it makes them to be forgotten.And the younger, she also bare a son, and called his name Benammi,.... That is, "the son of my people", being the son of her father; which though it does not so manifestly appear in this name, as in the other, yet there is some trace of it; and she would have it be known by this, that he was not the son of a stranger, but of a relation of her own: some attribute this to her being more modest than her elder sister; but it looks as if neither of them were sensible of any crime they had been guilty of, but rather thought it a commendable action, at least that it was excusable:

the same is the father of the children of Ammon unto this day; a people that lived near their brethren the Moabites, and were both enemies to the people of God; they quickly falling into idolatry, and whose names we often meet with in the sacred writings; and of these two sons, Josephus says (x), the one begat the Moabites, being still a great nation, and the other the Ammonites, and both inhabit Coelesyria; they are both called the children of Lot, Psalm 83:8. After this we hear no more of Lot in this history; and it is remarkable, that there never was, as we know of, any town or city that had in it any, trace of his name; but we are not from hence to conclude that he was a wicked man, whose memory perished with him; for mention is made of him in the New Testament, where he has a very honourable character, and is called "just Lot", 2 Peter 2:7.
