Song of Songs 8:6-7
6 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.

7 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.

love conquers all obstacles.
