For the commandment [is] a lamp; and the law [is] light; and reproofs of instruction [are] the way of life:
Ver. 23. For the commandment is a lamp.] Or, Candle, whereof there is no small use when men go to bed, or rise early. He that hath the word of Christ richly dwelling in him may lay his hand upon his heart, and say as dying Oecolampadius did, Hic sat lucis; here is plenty of light. Under the law all was in riddles; Moses was veiled; and yet that saying was then verified, Et latet et lucet. There was light enough to light men to Christ, "the end of the law." Rom 10:4
And reproofs of instruction.] Or, Corrections of instructions. A lesson set on with a whipping is best remembered. See Trapp on " Pro 3:13 "
