Song of Songs 8:5-8

Who is this coming out of the desert, leaning on her lover? I woke you under the apple tree where you were born; there your mother gave birth to you. Put me like a seal on your heart, like a seal on your arm. Love is as strong as death; jealousy is as strong as the grave. Love bursts into flames and burns like a hot fire. Even much water cannot put out the flame of love; floods cannot drown love. If a man offered everything in his house for love, people would totally reject it. We have a little sister, and her breasts are not yet grown. What should we do for our sister on the day she becomes engaged?
