Song of Solomon 8:6-7New King James Version (NKJV)
The Shulamite to Her Beloved
6 Set me as a seal upon your heart,
As a seal upon your arm;
For love is as strong as death,
Jealousy as cruel as the grave;
Its flames are flames of fire,
A most vehement flame.
7 Many waters cannot quench love,
Nor can the floods drown it.
If a man would give for love
All the wealth of his house,
It would be utterly despised.
