I adjure you, O daughters of Jerusalem,
that you not stir up or awaken love
until it pleases.

Who is that coming up from the wilderness,
leaning on her beloved?

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

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. (ESV)
