Their tongue is a deadly arrow; it speaketh deceit: one speaketh peaceably to his neighbor with his mouth, but in his heart he layeth wait for him.

King James Version (KJV):
Their tongue [is as] an arrow shot out; it speaketh deceit: [one] speaketh peaceably to his neighbour with his mouth, but in heart he layeth his wait.
