Their tongues are deadly arrows; they speak deception. With his mouth a man speaks peace to his neighbor, but in his heart he sets a trap for him.
Jewish Publication Society of America Version (JPS1917) - Jeremiah 9:8 >(9-7) Their tongue is a sharpened arrow, it speaketh deceit; one speaketh peaceably to his neighbour with his mouth, but in his heart he layeth wait for him.
