Song of Solomon 8:6-8

⁶Put me as a seal upon thy heart, as a seal upon thy arm, for love is strong as death, jealousy as hard as hell, the lamps thereof are fire and flames.

⁷Many waters cannot quench charity, neither can the floods drown it: if a man should give all the substance of his house for love, he shall despise it as nothing.

⁸Our sister is little, and hath no breasts. What shall we do to our sister in the day when she is to be spoken to?
