[18:15] 1 tn Heb “discerning heart.” The term “heart” is a synecdoche of part (= heart) for the whole (= person); cf. TEV, NLT “intelligent people.” By paralleling “heart” and “ear” the proverb stresses the full acquisition of knowledge. The “ear” listens to instruction, and the heart considers what is heard to acquire knowledge.
[18:15] 2 tn Heb “the ear of the wise.” The term “ear” is a synecdoche of part (= ear) for the whole (= person): “wise person.”
[18:15] sn The wise continually seek more knowledge. D. Kidner says, “Those who know most know best how little they know” (Proverbs [TOTC], 129).
[18:15] 3 sn This line features a mixed metaphor: The “ear” is pictured “seeking.” The “ear of the wise” actually means the wise person’s capacity to hear, and so the wise are seeking as they hear.
