John Gill Bible Commentary

BETH.--The Second Part. BETH. Wherewith shall a young man cleanse his way?.... Some think David means himself, and that he was a young man when he wrote this psalm; and which they think is confirmed by Psa 119:100; but neither of them seem conclusive; rather any young man is meant, and who is particularly mentioned, because young men are liable to sins and snares, to carnal lusts and sensual pleasures, which are of a defiling nature. Some are of opinion that a young man, or babe in Christ, is intended, that needs direction in his way, and instruction about the manner of cleansing it. But the former sense seems best, and expresses the concern of the psalmist for the education and right information of youth; which is a matter of great moment and advantage to families, neighbourhoods, and commonwealths. The question supposes the young man to be impure, as every man is by birth, being conceived in sin, and shapen in iniquity; is a transgressor from the womb, and his heart, ways, and actions, evil from his youth: and the difficulty is, how he shall be cleansed; how one so impure in his nature, heart, and ways, can be just with God, or become undefiled in the way, as in Psa 119:1; to which some reference may be had: or how he can have his heart made pure, or a clean one be created in him; or how his way, life, and conversation, may be corrected, reformed, and amended. The answer is, by taking heed thereto according to thy word; that is, to his way and course of life, and steering it according to the direction of the word of God. But I think the words may be better rendered and supplied thus, "by observing what is according to thy word" (p); which shows how a sinner is to be cleansed from his sins by the blood of Christ, and justified by his righteousness, and be clean through his word; and also how and by whom the work of sanctification is wrought in the heart, even by the Spirit of God, by means of the word; and what is the rule of a man's walk and conversation: he will find the word of God to be profitable, to inform in the doctrines of justification and pardon, to acquaint him with the nature of regeneration and sanctification; and for the correction and amendment of his life and manners, and for his instruction in every branch of righteousness, Ti2 3:16.
