Set me as a seal over your heart, as a seal upon your arm. For love is as strong as death, its jealousy as unrelenting as Sheol. Its sparks are fiery flames, the fiercest blaze of all.
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.
