Set me as a seal upon your heart, as a seal upon your arm: for love is as strong as death; jealousy is cruel as the grave: its flames are flames of fire, a most vehement flame.
All Commentaries on Song of Songs 8:6 Go To Song of Songs 8
Gregory The Dialogist
AD 604
Just as death destroys the body, so ardent desire for eternal life cuts off the love of material things. It renders one whom it has perfectly taken hold of insensible to earthly desires which come from without.
