Observe, 1. Wisdom and grace are the honour of good men: He that has understanding, that good understanding which those have that do the commandments, wisdom is found in his lips, that is, it is discovered to be there, and consequently that he has within a good treasure of it, and it is derived thence for the benefit of others. It is a man's honour to have wisdom, but much more to be instrumental to make others wise. 2. Folly and sin are the shame of bad men: A rod is for the back of him that is void of understanding - of him that wants a heart; he exposes himself to the lashes of his own conscience, to the scourges of the tongue, to the censures of the magistrate, and to the righteous judgments of God. Those that foolishly and wilfully go on in wicked ways are preparing rods for themselves, the marks of which will be their perpetual disgrace.
