Song of Solomon 8:4-6

Revised Standard Version

Under the apple tree I awakened you.
There your mother was in travail with you,
    there she who bore you was in travail.

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.
