Song of Solomon 8:6-8 Revised Standard Version Catholic Edition (RSVCE)
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.
8 We have a little sister,
and she has no breasts.
What shall we do for our sister,
on the day when she is spoken for?
