"Set me as a seal upon your heart,
as a seal upon your arm,
for love is strong as death,
jealousy is fierce as the grave.
Its flashes are flashes of fire,
the very flame of the Lord.
Many waters cannot quench love,
neither can floods drown it.
If a man offered for love
all the wealth of his house,
he would be utterly despised."
The Song of Songs 8:6-7
