Song of Solomon 8:6

Set me as a seal upon thine heart, as a seal upon thine arm: for love is strong as death; jealousy is cruel as the grave: the coals thereof are coals of fire, which hath a most vehement flame.

Seal - having her name or likeness engraven on it. His holy priesthood also in heaven, (; "His heart" there answering to "thine heart" here, and "two shoulders" to "arm." Compare with . The Church is sealed by the Holy Spirit (Ephesians 1:13). As in she was "leaning" on Him-i.e, her arm on His arm, her head on His bosom-so she prays now that her impression may be engraven both on His heart and His arm, answering to His love and His power (; see ).

Love is strong as death - (Romans 8:35.) This their love unto death flows from His love unto death (; ).

Cruel - Hebrew, quasha: rather, unyielding, hard: as the grave will not let go those whom it once holds ().

A most vehement flame - literature, the fire-flame of Yah or Yahweh (). Nowhere else is God's name found in the Song. The zeal that burnt in Jesus Christ kindled in His followers ().
