“Set me as a seal on your heart, as a seal on your arm; for love is strong as death. Jealousy is as cruel as Sheol. Its flashes are flashes of fire, A VERY FLAME OF YAHWEH.” Song of Songs 8:6-7 WEB

SEAL : A symbol of something especially dear and precious. See Jeremiah 22:24; Haggai 2:23, &c.

JEALOUSY : Strong passion, from a word meaning to be red with flame; not in a bad sense, as the parallelism shows:— “Strong as death is love, Inexorable as Sheol is ardent passion.”

GRAVE : Hebrew: sheôl. Perhaps, as in the LXX., Hades, with its figurative gates and bars (Psalm 6:5, Note).

COALS : Hebre: resheph; in Psalm 78:48, hot thunderbolts (comp. Habakkuk 3:5); in Job 5:7, sparks; sons of the burning;

A MOST VEHEMENT FLAME : Literally, A FLAME OF YAH, the only place where this sacred name occurs in the book, and here, as in the Authorised Version, adverbially, to express something superlatively great and strong. (Ellicott’s Commentary for English Readers)

A most vehement flame, Hebrews, shalhebheth yâh, a flame of Yah, i.e. a flame of supernatural power, one that is kindled and cherished by God. He goes on to describe it as an all-pervading Fire, kindled by the Eternal One, and partaking of His essence: “Its brands are brands of fire, A lightning-flash from Yah.” Compare Deuteronomy 4:24. This divine principle is next represented as overcoming in its might all opposing agencies whatsoever. (Barne’s Notes)

“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.” Song of Songs 8:6-7 NIV

“Place me like a seal over your heart, like a seal on your arm. For love is as strong as death, its jealousy as enduring as the grave. Love flashes like fire, the brightest kind of flame.” Song of Songs 8:6-7 NLT

“Therefore, since we are receiving an unshakable kingdom, let us be filled with gratitude, and so worship God acceptably with reverence and awe. “For our God is a consuming fire.” Hebrews 12:28-29.

“Sing, O heavens; and be joyful, O earth; and break forth into singing, O mountains: for The LORD has comforted His people, and will have mercy upon His afflicted. But Zion said, “The LORD hath forsaken me, and my Lord hath forgotten me.” Can a woman forget her nursing child, that she should not have compassion on the son of her womb? yea, they may forget, yet will I not forget you. Behold, I have graven you upon the palms of My Hands; your walls are continually before Me.” Isaiah 49:13-16.

“Yahweh came from Teman, and the Holy One from Mount Paran. Selah. His glory covered the heavens, and His praise filled the earth. His radiance was like the sunlight; RAYS flashed from His hand, where His power is hidden.” Habakkuk 3:3-4.

“Bend down Your heavens, LORD, and come down; touch the mountains, that they may smoke.
Flash forth LIGHTNING and scatter them; send out Your arrows and confuse them. Reach out with Your hand from on high; rescue me and save me from great waters, From the hand of foreigners whose mouths speak deceit, and whose right hand is a right hand of falsehood.” Psalm 144:5-8.
