Buy {k} the truth, and sell it not; also wisdom, and instruction, and understanding.

(k) Spare no cost for truths sake, neither depart from it for any gain.

Wesley's Notes

23:23 Buy - Purchase it upon any terms, spare no pains or cost. Truth - The true and saving knowledge of God's will. Sell it not - Do not forsake it for any worldly advantage.

Jamieson-Fausset-Brown Bible Commentary

23. Buy-literally, "get" (Pr 4:5).

truth-generally and specially as opposed to errors of all kinds.

Matthew Henry's Concise Commentary

23:19-28 The gracious Saviour who purchased pardon and peace for his people, with all the affection of a tender parent, counsels us to hear and be wise, and is ready to guide our hearts in his way. Here we have an earnest call to young people, to attend to the advice of their godly parents. If the heart be guided, the steps will be guided. Buy the truth, and sell it not; be willing to part with any thing for it. Do not part with it for pleasures, honours, riches, or any thing in this world. The heart is what the great God requires. We must not think to divide the heart between God and the world; he will have all or none. Look to the rule of God's word, the conduct of his providence, and the good examples of his people. Particular cautions are given against sins most destructive to wisdom and grace in the soul. It is really a shame to make a god of the belly. Drunkenness stupifies men, and then all goes to ruin. Licentiousness takes away the heart that should be given to God. Take heed of any approaches toward this sin, it is very hard to retreat from it. It bewitches men to their ruin.
