For the commandment is a lamp; and the law is light; and reproofs of instruction are the way of life:
– Proverbs 6:23
Solomon is not merely speaking of the homespun wisdom of the older generation. He is talking about God’s word and the wisdom in it. Commandment, law, and instruction are references to God’s word (Psalm 119:105). He is still mentioning benefits of wisdom and this verse explains the previous one. Lamp, light, and way of life speak of illuminating and guiding in the wise course of life. Reproofs are corrections that come through instruction, so wisdom provides a continual course corrective as we proceed through life.
