Genesis 9:18

The drunkenness of Noah is recorded in the Bible, with that fairness which is found only in the Scripture, as a case and proof of human weakness and imperfection, even though he may have been surprised into the sin; and to show that the best of men cannot stand upright, unless they depend upon Divine grace, and are upheld thereby. Ham appears to have been a bad man, and probably rejoiced to find his father in an unbecoming situation. It was said of Noah, that he was perfect in his generations, ch. 6:9; but this is meant of sincerity, not of a sinless perfection. Noah, who had kept sober in drunken company, is now drunk in sober company. Let him that thinks he stands, take heed lest he fall. We have need to be very careful when we use God's good creatures plentifully, lest we use them to excess, Lu 21:34. The consequence of Noah's sin was shame. Observe here the great evil of the sin of drunkenness. It discovers men; what infirmities they have, they betray when they are drunk; and secrets are then easily got out of them. Drunken porters keep open gates. It disgraces men, and exposes them to contempt. As it shows them, so it shames them. Men say and do that when drunken, which, when sober, they would blush to think of. Notice the care of Shem and Japheth to cover their father's shame. There is a mantle of love to be thrown over the faults of all, 1Pe 4:8. Beside that, there is a robe of reverence to be thrown over the faults of parents and other superiors. The blessing of God attends on those who honour their parents, and his curse lights especially on those who dishonour them.
