As suggested by the BCP:
Song of Solomon 2:10-13; 8:6-7
My beloved speaks and says to me: Arise, my love, my fair one, and come away; for now the winter is past, the rain is over and gone. The flowers appear on the earth; the time of singing has come, and the voice of the turtledove is heard in our land. The fig tree puts forth its figs, and the vines are in blossom; they give forth fragrance. Arise, my love, my fair one, and come away.
Set me as a seal upon your heart, as a seal upon your arm; for love is strong as death, passion fierce as the grave. Its flashes are flashes of fire, a raging flame. Many waters cannot quench love, neither can floods drown it. If one offered for love all the wealth of his house, it would be utterly scorned.
