33 So they made their father drink wine that night; and the first-born went in, and lay with her father; he did not know when she lay down or when she arose. 34 And on the next day, the first-born said to the younger, "Behold, I lay last night with my father; let us make him drink wine tonight also; then you go in and lie with him, that we may preserve offspring through our father." 35 So they made their father drink wine that night also; and the younger arose, and lay with him; and he did not know when she lay down or when she arose.

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.
