2. It makes men impure and insolent, v. 33. (1.) The eyes grow unruly and behold strange women to lust after them, and so let in adultery into the heart. Est Venus in vinis—Wine is oil to the fire of lust. Thy eyes shall behold strange things (so some read it); when men are drunk the house turns round with them, and every thing looks strange to them, so that them they cannot trust their own eyes. (2.) The tongue also grows unruly and talks extravagantly; by it the heart utters perverse things, things contrary to reason, religion, and common civility, which they would be ashamed to speak if they were sober. What ridiculous incoherent nonsense men will talk when they are drunk who at another time will speak admirably well and to the purpose!

Matthew Henry Commentary on the Whole Bible (Concise) (Matthew Henry)

Verses 29-35 Solomon warns against drunkenness. Those that would be kept from sin, must keep from all the beginnings of it, and fear coming within reach of its allurements. Foresee the punishment, what it will at last end in, if repentance prevent not. It makes men quarrel. Drunkards wilfully make woe and sorrow for themselves. It makes men impure and insolent. The tongue grows unruly; the heart utters things contrary to reason, religion, and common civility. It stupifies and besots men. They are in danger of death, of damnation; as much exposed as if they slept upon the top of a mast, yet feel secure. They fear no peril when the terrors of the Lord are before them; they feel no pain when the judgments of God are actually upon them. So lost is a drunkard to virtue and honour, so wretchedly is his conscience seared, that he is not ashamed to say, I will seek it again. With good reason we were bid to stop before the beginning. Who that has common sense would contract a habit, or sell himself to a sin, which tends to such guilt and misery, and exposes a man every day to the danger of dying insensible, and awaking in hell? Wisdom seems in these chapters to take up the discourse as at the beginning of the book. They must be considered as the words of Christ to the sinner.
