Passage
His left hand [is] under my head, And his right hand doth embrace me.
His left hand [is] under my head, And his right hand doth embrace me.
Song of Solomon 2:4 He brought me to the banqueting-house, And his banner over me was love.
Song of Solomon 2:5 Stay ye me with raisins, refresh me with apples; For I am sick from love.
Song of Solomon 2:6 His left hand [is] under my head, And his right hand doth embrace me.
Song of Solomon 2:7 I adjure you, O daughters of Jerusalem, By the roes, or by the hinds of the field, That ye stir not up, nor awake [my] love, Until he please.
Song of Solomon 2:8 The voice of my beloved! behold, he cometh, Leaping upon the mountains, Skipping upon the hills.
The verse centers on "left", "hand", "under", "head", "right", "doth", and "embrace". It is saying that the verse draws attention to "left" and "hand", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 5's "Stay ye me with raisins refresh me..." into verse 7's "I adjure you O daughters of Jerusalem...", so "left" and "hand" 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 "left" and "hand" with trust shaped by these words, not by a vague optimism outside the passage.
