Song of Songs 8:6-7

6Put me like a 1seal over your heart, Like a 2seal on your arm. For love is as strong as death, 34Jealousy is as severe as Sheol; Its flashes are flashes of fire, 5The very flame of the Lord.7Many waters cannot quench love, Nor will rivers overflow it; 6If a man were to give all the riches of his house for love, It would be utterly despised.”
