¶ Set me as a seal upon thine heart, as a seal upon thine arm: for love [is] strong as death; jealousy [is] cruel as the grave: the coals thereof [are] coals of fire, [which hath a] most vehement flame.
Jewish Publication Society of America Version (JPS1917) - Song of Solomon 8:6 >Set me as a seal upon thy heart, as a seal upon thine arm; for love is strong as death, jealousy is cruel as the grave; the flashes thereof are flashes of fire, a very flame of the LORD.
