John Gill's Exposition of the Whole Bible
Proverbs 15:10
Correction [is] grievous unto him that forsaketh the way,.... The right way, the way of God; the way of his commandments: the Vulgate Latin version is, "the way of life"; the same with the way of righteousness, which apostates, having known and walked in, turn aside from; see 2 Peter 2:15. And such deserve severe correction, the chastisement of a cruel one, correction in wrath and hot displeasure; which, when they have, is very disagreeable to them; they behave under it like a bullock unaccustomed to the yoke, and yet they are but dealt righteously with. Or the words may be rendered, "he [has had] bad discipline" or "instruction z that forsakes the way"; due care has not been taken of him; he has not been properly instructed, nor seasonably corrected; had he, he would not easily have departed from the way in which he should go; see Proverbs 22:6. The Targum is,
"the discipline of an evil man causes his way to err;''
or him to err from his way;
[and] he that hateth reproof shall die; that hates the reproof of parents, masters, and ministers of the word; as he may be said to do that neglects and rejects it, and does not act agreeably to it: and such a man, dying in impenitence and without faith in Christ, dies in his sins; and sometimes shamefully, or a shameful death, as the Septuagint and Arabic versions, or an untimely one; as well as dies the second death, an eternal one.
