Vanity. — So in Psalms 41:6 and Job 35:13. Literally, evil. “Falsehood” would be better. This verse may have been in St Paul’s mind (Ephesians 4:25).
Flattering lips. — Literally, lips of smoothness, (Comp. Note, Psalms 5:9.)
With a double heart. — Literally, with a heart and a heart. (Comp. 1 Chronicles 12:33.) “One for the Church, another for the Change; one for Sundays, another for working-days; one for the king, another for the Pope. A man without a heart is a wonder, but a man with two hearts is a monster.” — Thos. Adams, A.D. 1614.
