John Gill's Exposition of the Whole Bible
Proverbs 13:18
Poverty and shame [shall be to] him that refuseth instruction,.... Of parents, masters, and ministers of the word; the instruction of wisdom, the instruction of the Gospel, in things relating to their present spiritual peace, and to their eternal welfare: such generally come to poverty and disgrace in this life, and to everlasting shame and contempt in another; see Proverbs 5:11;
but he that regardeth reproof; the reproof of the word, and of the ministers of it, and of all good men, and takes it kindly, and acts according to it,
shall be honoured; with riches and reputation; if not with the riches of this world, yet with the riches of grace and glory; and shall have honour among the saints, and from the Lord himself; who will honour those that honour him, as they do who regard the reproof and instruction of his word, 1 Samuel 2:30.
