Commentary on Proverbs 17:13

• Matthew Henry (Presbyterian), Matthew Henry's Complete Commentary on Proverbs 17:13: A malicious mischievous man is here represented, 1. As ungrateful to his friends. He oftentimes is so absurd and insensible of kindnesses done him that he renders evil for good. David met with those that were his adversaries for his love, Psa 109:4. To render evil for evil is brutish, but to render evil for good is devilish.
• John Gill (Reformed Baptist), Exposition of the Old and New Testaments on Proverbs 17:13: Whoso rewardeth evil for good,.... As the enemies of David and Christ rewarded them, Psa 35:12; this is base ingratitude, contrary to the law and light of nature; worse than beastly, is really devilish; evil shall not depart from his house; from him and his family; they shall be continually visited with one disease and calamity or another; so hateful and offensive is the sin...
• Jamieson-Fausset-Brown (Reformed), Commentary Critical and Explanatory on the Whole Bible on Proverbs 17:13: (Compare Psa 7:4; Psa 35:12). evil--injury to another (Pro 13:21).
• Keil & Delitzsch (Lutheran), Biblical Commentary on the Old Testament on Proverbs 17:13: Pro 17:13 13 He that returneth evil for good, From his house evil shall not depart. If ingratitude appertains to the sinful manifestations of ignoble selfishness, how much more sinful still is black ingratitude, which recompenses evil for good! (משׁיב, as 1Sa 25:21, syn. גּמל, to requite, Pro 3:30; Pro 31:12; שׁלּם, to reimburse, Pro 20:22).
