Proverbs 26:26-28 Living Bible (TLB)
24-26 A man with hate in his heart may sound pleasant enough, but don’t believe him; for he is cursing you in his heart. Though he pretends to be so kind, his hatred will finally come to light for all to see.
27 The man who sets a trap for others will get caught in it himself. Roll a boulder down on someone, and it will roll back and crush you.
28 Flattery is a form of hatred and wounds cruelly.
