Song of Songs 8:6-7 - The Nature Of Genuine Romantic Love
6 Set me as a seal upon your heart, as a seal upon your arm: for love is as strong as death; jealousy is cruel as the grave: its flames are flames of fire, a most vehement flame. 7 Many waters cannot quench love, neither can the floods drown it: if a man would give all the wealth of his house for love, it would utterly be rejected.
