Song of Songs

I'm reading the Song of Songs/the Song of Solomon for Bible as literature. This is one of my favorite parts:

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.
