Mishle 26:23-25

Orthodox Jewish Bible

²³ Fervent sfatayim (lips) and a lev rah are like earthenware covered with silver dross.

²⁴ He that hateth disguises it with his sfatayim (lips), and within harboreth mirmah (deceit);

²⁵ When he speaketh fair, believe him not; for there are sheva to’avot in his lev.
