literally, Cease, my son, to hear instruction, that thou mayest err from the words of knowledge; advice given ironically to do that to which his weakness leads him, with a clear knowledge of the evil to which he is drifting.

Cease, my son - Hear nothing that would lead thee away from God and his truth.

Cease, my son, to hear the instruction,.... The counsel of bad men, or the doctrine of false teachers. The words are spoken either by Solomon to his son; or by Wisdom, that is, Christ, to everyone of his children, to beware of false prophets, and take heed what they hear; see Matthew 7:15; such as the doctrines of the church of Rome; concerning the Scriptures, forbidding the people to read them; setting unwritten traditions upon a level with them, and making the pope an infallible interpreter of them; concerning merit, works of supererogation, indulgences, pardons, penance, purgatory, &c. such as the instruction of the Arians, Sabellians, Socinians, Pelagians, and Arminians, concerning the Trinity, the deity of Christ, his satisfaction, imputed righteousness, the power and purity of human nature, and man's free will;
that causeth to err from the words of knowledge; the words of the living God, the Scriptures of truth; which communicate knowledge, and are profitable for instruction in righteousness; are the means of the true knowledge of God; that there is one, and that he is possessed of all perfections: particularly that he is gracious and merciful, and pardons all manner of sin; that he is in Christ, the God of all grace; that he is the God and Father of Christ, and the covenant God and Father of all his people in him; they give knowledge of his mind and will concerning the salvation of men, and of his ways and worship. The wholesome words of our Lord Jesus, the salutary doctrines of the Gospel, may be here meant; those words of grace, wisdom, and knowledge, which come from him, and give knowledge of his person, offices, relations, incarnation, and blessings of grace by him; from whence they are called the word of peace and reconciliation, the word of righteousness, the word of life, and the word of salvation. Now these are all words of knowledge; and are the means of a spiritual, experimental, and fiducial knowledge of Christ, which is preferable to all other knowledge, and even to everything in the world; and therefore care should be taken, and everything avoided that tends to cause to err from these words and doctrines, which convey, promote, and improve this knowledge. Jarchi and Aben Ezra transpose the words, thus;
"cease, my son, to err from the words of knowledge, to or that thou mayest hear instruction and the latter makes mention of such an interpretation, cease, my son, from the words of knowledge, if thou wouldest hear instruction, and after that err:''
that is, better never hear and know at all, than to turn from those doctrines and instructions; see 2-Peter 2:20.

It is the wisdom of young men to dread hearing such talk as puts loose and evil principles into the mind.

Avoid whatever leads from truth.

27 Cease, my son, to hear instruction,
To depart from the words of knowledge.
Oetinger correctly: cease from hearing instruction if thou wilt make no other use of it than to depart, etc., i.e., cease to learn wisdom and afterwards to misuse it. The proverb is, as Ewald says, as "bloody irony;" but it is a dissuasive from hypocrisy, a warning against the self-deception of which James 1:22-24 speaks, against heightening one's own condemnation, which is the case of that servant who knows his lord's will and does it not, Luke 12:47. חדל, in the meaning to leave off doing something further, is more frequently construed with ל seq. infin. than with מן (cf. e.g., Genesis 11:8 with 1-Kings 15:21); but if we mean the omission of a thing which has not yet been begun, then the construction is with ל, Numbers 9:13, Instead of לשׁגּות, there might have been also used מלּשׁגּות (omit rather than...), and למען שׁגות would be more distinct; but as the proverb is expressed, לשׁגות is not to be mistaken as the subord. infin. of purpose. The lxx, Syr., Targ., and Jerome do violence to the proverb. Luther, after the example of older interpreters: instruction, that which leads away from prudent learning; but musar always means either discipline weaning from evil, or education leading to good.
