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. Many waters cannot quench love, Neither can floods drown it: If a man would give all the substance of his house for love, He would utterly be contemned.
Song of Solomon 8:4 I adjure you, O daughters of Jerusalem, That ye stir not up, nor awake [my] love, Until he please.

Song of Solomon 8:6 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.
Song of Solomon 8:7 Many waters cannot quench love, Neither can floods drown it: If a man would give all the substance of his house for love, He would utterly be contemned.
Song of Solomon 8:8 We have a little sister, And she hath no breasts: What shall we do for our sister In the day when she shall be spoken for?
Song of Solomon 8:9 If she be a wall, We will build upon her a turret of silver: And if she be a door, We will inclose her with boards of cedar.
The verse centers on "seal", "upon", "heart", "thine", "love", and "strong". It is saying that the verse draws attention to "seal" and "upon", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 5's "Who is this that cometh up from..." into verse 8's "We have a little sister And she...", so "seal" and "upon" belong inside that flow. In Song of Solomon context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "seal" and "upon" with trust shaped by these words, not by a vague optimism outside the passage.
