Proverbs 23:30

So he adds these most monitory words. “Who has woes, who has clamour, who has contentions, who has disgusting babblings, who has unavailing remorse?” You see, in all his raggedness, the lover of wine, who despises the Word Himself, and has abandoned and given himself to drunkenness. You see what threatening Scripture has pronounced against him. And to its threatening it adds again: “Whose are red eyes? Those, is it not, who tarry long at their wine, and hunt out the places where drinking goes on?” Here he shows the lover of drink to be already dead to the Word, by the mention of the bloodshot eyes, a mark which appears on corpses, announcing to him death in the Lord.
