² tn In Lam 4:7 these are described as red, and so have been identified as rubies (so NIV) or corals.

¹ tc The MT reads רָאמוֹת (raʾmot, “corals”)—wisdom to the fool is corals, i.e., an unattainable treasure. With a slight change in the text, removing the א (ʾalef), the reading is רָמוֹת (ramot, “high”), i.e., wisdom is too high—unattainable—for a fool. The internal evidence favors the emendation, which is followed by most English versions including KJV.

¹ tn The verse is usually taken as antithetical parallelism: There may be gold and rubies but the true gem is knowledge. However, C. H. Toy arranges it differently: “store of gold and wealth of corals and precious vessels—all are wise lips” (Proverbs [ICC], 388). But this uses the gems as metaphors for wise speech, and does not stress the contrast between wealth and wisdom.
