Matthew Henry Commentary Proverbs 10:5-6

"He that gathereth in summer is a wise son; [But] he that sleepeth in harvest is a son that causeth shame. Blessings are upon the head of the righteous; But violence covereth the mouth of the wicked." — Proverbs 10:5-6 (ASV)

Plain and faithful rebukes are better, not only than secret hatred, but than love which flatters in sin, to the hurt of the soul.

The ways of wickedness are dangerous. And sin will be its own punishment.
