1 sn The eighteenth saying is about excessive drinking. The style changes here as the sage breaks into a vivid use of the imagination. It begins with a riddle describing the effects of drunkenness (v. 29) and gives the answer in v. 30; instructions follow in v. 31, with the consequences described in v. 32; the direct address continues in vv. 33 and 34; and the whole subject is concluded with the drunkard’s own words in v. 35 (M. E. Andrews, “Variety of Expression in Proverbs 23:29-35,” VT 28 [1978]: 102-3).
2 sn The Hebrew word translated “dullness” describes darkness or dullness of the eyes due to intoxication, perhaps “redness” (so KJV, NASB, NRSV); NIV, NCV, NLT “bloodshot eyes.” NAB understands the situation differently: “black eyes.”
3 sn The answer to the question posed in v. 29 is obviously one who drinks too much, which this verse uses metonymies to point out. Lingering over wine is an adjunct of drinking more wine; and seeking mixed wine obviously means with the effect or the purpose of drinking it.
