Song of Solomon 8:6-7

Set me as a seal upon thy heart, As a seal upon thine arm: For love is strong as death; Jealousy is cruel as Sheol; The flashes thereof are flashes of fire, A very flame of Jehovah. Many waters cannot quench love, Neither can floods drown it: If a man would give all the substance of his house for love, He would utterly be contemned.
