Set me as a seal over your heart, as a seal upon your arm. For love is as strong as death, its jealousy as unrelenting as Sheol. Its sparks are fiery flames, the fiercest blaze of all.
Set me as a seal upon thy heart, as a seal upon thy arm: for love [is] strong as death; jealousy [is] cruel as the grave: the coals of it [are] coals of fire, [which hath a] most vehement flame. (d) The spouse desires Christ to be joined in perpetual love with him.
Sol 8:6-7 After Solomon has thus called to remembrance the commencement of their love-relation, which receives again a special consecration by the reference to Shulamith’s parental home, and to her mother, Shulamith answers with a request to preserve for her this love. 6 Place me as a signet-ring on thy heart, As a signet-ring on thine arm!
