Song of Solomon 8:6-7

⁶Set me as a seal on thy heart, as a seal on thine arm, For strong as death is love, Sharp as Sheol is jealousy, Its burnings are burnings of fire, a flame of Jah!

⁷Many waters are not able to quench the love, And floods do not wash it away. If one give all the wealth of his house for love, Treading down — they tread upon it.
