1 tn Heb “discipline.” The noun מוּסָר (musar) has a basic two-fold range of meanings: (1) “discipline” (so NIV; NAB “admonition”; NCV, NLT “correction”) and (2) “instruction” (BDB 416 s.v.; so KJV, NASB, NRSV). The wise person listens to instruction (first colon); however, the fool will not even take discipline to heart (second colon).
2 tn The term is a genitive of location indicating the goal (IBHS 147-48 §9.5.2f).
3 sn The contrast with the one who holds fast to discipline is the one who forsakes or abandons reproof or correction. Whereas the first is an example, this latter individual causes people to wander from the true course of life, that is, causes them to err.
