Jeremiah 9:7
Jewish Publication Society 1917 · Berean Standard Bible
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.
9:8
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.
