Song of Songs 8:6-7 - The Nature Of Genuine Romantic Love
6 Set me as a seal upon thine heart as a sign upon thine arm; for love is strong as death; jealousy is hard as Sheol; the coals thereof are coals of fire, which have a most vehement flame. 7 The many waters cannot quench love, neither can the rivers drown it; if a man would give all the substance of his house for this love, it would certainly be despised.
