Burning lips and a wicked heart are like a potsherd covered with silver dross. He that hateth dissembleth with his lips, and layeth up deceit within him; When he speaketh fair, believe him not: for there are seven abominations in his heart. Whose hatred is covered by deceit, his wickedness shall be shewed before the whole congregation.
Flapping lips, with a wicked heart, is like a clay pot covered with silver dross. A shining, silvery finish disguises the worthlessness and drabness of the pot underneath. Flapping lips, with phony or pretend love, often covers a heart full of hatred. Unfortunately, once that individual is found out, it is difficult to trust anything they say or do.
