Like A Seal On His Heart - Song Of Songs

This Christian Song is taken from the last chapter 8 of Song of Songs - verses 6 and 7
Place me like a seal over your heart,
like a seal on your arm;
for love is as strong as death
its jealousy unyielding as the grave.
It burns like blazing fire,
like a mighty flame.
7Many waters cannot quench love;
rivers cannot sweep it away.
This also quotes Romans 8 about how noting can separate us from our Lord.
