31 And the first-born saith unto the younger, 'Our father 'is' old, and a man there is not in the earth to come in unto us, as 'is' the way of all the earth; 32 come, we cause our father to drink wine, and lie with him, and preserve from our father—a seed.' 33 And they cause their father to drink wine on that night; and the first-born goeth in, and lieth with her father, and he hath not known in her lying down, or in her rising up. 34 And it cometh to pass, on the morrow, that the first-born saith unto the younger, 'Lo, I have lain yesterday-night with my father: we cause him to drink wine also to-night, and go thou in, lie with him, and we preserve from our father—a seed.' 35 And they cause their father to drink wine on that night also, and the younger riseth and lieth with him, and he hath not known in her lying down, or in her rising up.

Commentary on Genesis 19:30-38
(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.
