American Standard Version (ASV):
Set me as a seal upon thy heart, As a seal upon thine arm: For love is strong as death; Jealousy is cruel as Sheol; The flashes thereof are flashes of fire, A very flame of Jehovah.
King James Version (KJV):
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.
