Render as a wish or prayer: "O that his left hand were under my head, and that his right hand did embrace me!" Let him draw me to him with entire affection. Compare Deuteronomy 33:27; Proverbs 4:8.

His left hand is under my head, and his right hand doth embrace me. The church, having desired to be stayed, supported, strengthened, and comforted, presently found her beloved with her, who with both hands sustained her; which shows his tender love to her, care of her, and regard for her; and is expressive of the near and intimate communion she had with him, as the effect of union to him, often enjoyed in his house and ordinances; likewise of blessings of every kind she received from him; temporal, mercies, or left hand blessings, which are necessary to support and carry through this wilderness; and spiritual, or right hand blessings, as justification, pardon, adoption, &c. and, moreover, may denote the safety and security of the church, being encircled in the arms of her beloved, sustained by Christ's left hand, and embraced by his right hand, out of whose hands none can pluck. Some read the words prayer wise, "let his left hand be", &c. (b); still desiring further tokens of his love to her, and more and nearer communion with him: others read it in the future, "his left hand will be", &c. (c); "his right hand shall embrace", &c. expressing the strength of her faith that she should for the future enjoy his gracious presence; and that he would support her, that she should not sink and faint.
(b) Tigurine version, some in Mercer. Marckius; so Ainsworth. (c) V. L. Pagninus Montanus.

The "stay" she prayed for (Song 2:5) is granted (Deuteronomy 33:12, Deuteronomy 33:27; Psalm 37:24; Isaiah 41:16). None can pluck from that embrace (John 10:28-30). His hand keeps us from falling (Matthew 14:30-31); to it we may commit ourselves (Psalm 31:5).
left hand--the left is the inferior hand, by which the Lord less signally manifests His love, than by the right; the secret hand of ordinary providence, as distinguished from that of manifested grace (the "right"). They really go together, though sometimes they seem divided; here both are felt at once. THEODORET takes the left hand, equivalent to judgment and wrath; the right, equivalent to honor and love. The hand of justice no longer is lifted to smite, but is under the head of the believer to support (Isaiah 42:21); the hand of Jesus Christ pierced by justice for our sin supports us. The charge not to disturb the beloved occurs thrice: but the sentiment here, "His left hand," &c., nowhere else fully; which accords with the intensity of joy (Song 2:5) found nowhere else; in Song 8:3, it is only conditional, "should embrace," not "doth."

6 His left hand is under my head,
And his right hand doth embrace me.
With his left hand he supports her head that had fallen backwards, and with his right he embraces her [herzet], as Luther rightly renders it (as he also renders the name Habakkuk by "der Herzer" = the embracer); for חבּק signifies properly to enfold, to embrace; but then generally, to embrace lovingly, to fondle, of that gentle stroking with the hand elsewhere denoted by חלּה, mulcere. The situation here is like that at Genesis 29:13; Genesis 48:10; where, connected with the dat., it is meant of loving arms stretched out to embrace. If this sympathetic, gentle embracing exercises a soothing influence on her, overcome by the power of her emotions; so love mutually kindled now celebrates the first hour of delighted enjoyment, and the happy Shulamith calls to those who are witnesses of her joy:

His hand - No sooner did I cry out for help, but he was at hand to succour me.
