Love is as strong as death...

Song of Solomon 8:6-7
Place me like a seal over your heart, like a seal on your arm; for love is as strong as death, its jealousy unyielding as the grave. It burns like blazing fire, like a mighty flame. Many waters cannot quench love; rivers cannot wash it away. If one were to give all the wealth of his house for love, it would be utterly scorned.
