Song of Solomon 8:6-7

“Put me like a seal over your heart, Like a seal on your arm. For love is as strong as death, Jealousy is as severe as Sheol; Its flames are flames of fire, The flame of the LORD. “Many waters cannot quench love, Nor will rivers flood over it; If a man were to give all the riches of his house for love, It would be utterly despised.”
