30 Then Lot went up out of Zoar to the mountain, and was living there with his two daughters, for fear kept him from living in Zoar: and he and his daughters made their living-place in a hole in the rock. 31 And the older daughter said to her sister, Our father is old, and there is no man to be a husband to us in the natural way: 32 Come, let us give our father much wine, and we will go into his bed, so that we may have offspring by our father, 33 And that night they made their father take much wine; and the older daughter went into his bed; and he had no knowledge of when she went in or when she went away. 34 And on the day after, the older daughter said to the younger, Last night I was with my father; let us make him take much wine this night again, and do you go to him, so that we may have offspring by our father. 35 And that night again they made their father take much wine; and the younger daughter went into his bed; and he had no knowledge of when she went in or when she went away. 36 And so the two daughters of Lot were with child by their father. 37 And the older daughter had a son, and she gave him the name Moab: he is the father of the Moabites to this day. 38 And the younger had a son and gave him the name Ben-ammi: from him come the children of Ammon to this day.

(Read Genesis 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.
