To know wisdom and instruction; to perceive the words of understanding;
To know wisdom - depending on Proverbs 1:1. The proverbs of Solomon are designed that all may by them know wisdom.
And instruction, х uwmuwcaar (H4148)] - from a Hebrew root, yaacar (H3256), to chastise or correct by discipline and admonition (like paideuein, paideia (G3809) "discipline in righteousness," 2 Timothy 3:15; cf. Proverbs 13:18; Proverbs 13:24; Proverbs 22:15). "Wisdom" is the general term for the knowledge that "maketh wise unto salvation" (2 Timothy 3:15). In a more special sense, "wisdom" is knowledge of divine truth in both the head and the heart х chaakªmaah (H2451)] - cf. 1 Corinthians 12:8. "Instruction" is the tutoring of one in the application of the principles of piety to the daily practice. So Lyra and the Hebrew commentators in Mercer explain.

To perceive the words of understandings, х biynaah (H998)] - whereby you may discreetly discern between good and bad, the lawful and the unlawful, the useful and the hurtful, the true and the false, and may know what you ought and what you ought not to do in every circumstance (Cornelius a Lapide). "Understanding" [from a root, bin or bun, akin to the particle beeyn, 'between,' to judge concerning differences, to distinguish between, to consider internally with the mind-sunienai sunesis] differs from "wisdom," in that by wisdom things are surely known; by "understanding," things that differ are prudently discerned, and a discriminating judgment is formed on them after inward consideration.
