For my mouth shall speak truth; and wickedness is an abomination to my lips.
For my mouth (Hebrew, palate) shall speak truth; and wickedness (is) an abomination to my lips. "Speak" - literally, 'meditate.' I will not speak rashly, but with premeditation; implying the meditative thoughtfulness and gravity of the speaker's words. The antithetical contrast to "truth" shows that "wickedness" refers here to lying or error, which is the associate of impiety. Every lie, even in jest, or though sanctioned by the world's fashion, is "wickedness." Piety not only speaks the truth, but does so from the love of the truth and hatred of falsehood: not for the sake of gain or honour, or through fear of man.
