A righteous person hates a deceptive word, but a wicked person will become a stench and display his shame.
“become a stench.” This is a graphic and idiomatic way to say that wicked people will be hated (cp. HALOT Hebrew-English Lexicon). Wicked people stink to the righteous. Interestingly, righteous people stink to the wicked (2 Cor. 2:16).
