Matthew Henry's Complete Bible Commentary

Verse 19

1. As we read this, it intimates, in short, that angry men never want woe. Those that are of strong, or rather headstrong, passions, commonly bring themselves and their families into trouble by vexatious suits and quarrels and the provocations they give; they are still smarting, in one instance or other, for their ungoverned heats; and, if their friends deliver them out of one trouble, they will quickly involve themselves in another, and they must do it again, all which troubles to themselves and others would be prevented if they would mortify their passions and get the rule of their own spirits. 2. It may as well be read, He that is of great wrath (meaning the child that is to be corrected and is impatient of rebuke, cries and makes a noise, even that wrath of his against the rod of correction) deserves to be punished; for, if thou deliver him for the sake of that, thou wilt be forced to punish him so much the more next time. A stomachful high-spirited child must be subdued betimes, or it will be the worse for it. MHBCC 648.19
