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 Psalm 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 Psalm 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"
