Song of Songs 8:5-6

5 Who is this one?  She arises out of her desert, clinging to her beloved.  When I awakened you under the apple tree, as you were feasting upon me, I awakened your innermost being with the travail of birth as you longed for more of me.  

6 Fasten me upon your heart as a seal of fire forevermore.  This living, consuming flame will seal you as my prisoner of love.  My passion is stronger than the chains of death and the grave, all consuming as the very flashes of fire from the burning heart of God.  Place this fierce, unrelenting fire over your entire being.
