He that spareth, Heb. withholdeth it from his son when it is due to him, his rod, that correction which his son's fault requires, and he as a father is required to give him, hateth his son; not directly and properly in regard of his affection, but consequently, and in respect of the event. His fond affection is as pernicious to him as his or another man's hatred could be. Chasteneth him betimes; either,
1. In his tender years, as soon as he is capable of it. Or,
2. Speedily, before he be hardened and inveterate in sin. God's favour and blessing gives the righteous man a competent estate, and a heart to use it, and comfort and satisfaction in it; whereas wicked men commonly want either all these blessings, or some of them.
