Song of Solomon 8:6-7

Revised Standard Version Catholic Edition

⁶ Set me as a seal upon your heart,
    as a seal upon your arm;
for love is strong as death,
    jealousy is cruel as the grave.
Its flashes are flashes of fire,
    a most vehement flame.
⁷ Many waters cannot quench love,
    neither can floods drown it.
If a man offered for love
    all the wealth of his house,
    it would be utterly scorned.
