What does Proverbs 26:25 mean?

Solomon counsels his readers to reject an evil man's gracious words. So far, this passage referred to those disguising hate and malice with deceptive appearances. This is like a thin glaze on pottery (Proverbs 26:23). Those who hide evil with their words express hate for others (Proverbs 26:24), since their actions are a betrayal. This is the kind of person about whom Solomon (Proverbs 25:1) warns here.

Satan is a master of disguising evil to appear good. It's the way he deceived Eve (Genesis 3:6). We cannot always know who is lying or telling the truth. We also want to be ready to offer forgiveness and grace (Matthew 5:24; 6:14–15). However, when someone has proven deceitful or hateful, it's wise not to trust their words. Even if what they say is "gracious," or attractive, their reputation says otherwise. The "seven abominations" mentioned here might be a reference to the list given in Proverbs 6:16–19.
