8:5-7 The Jewish church came up from the wilderness, supported by Divine power and favour. The Christian church was raised from a low, desolate condition, by the grace of Christ relied on. Believers, by the power of grace, are brought up from the wilderness. A sinful state is a wilderness in which there is no true comfort; it is a wandering, wanting state: There is no coming out of this wilderness, but leaning on Christ as our Beloved, by faith; not leaning to our own understanding, nor trusting in any righteousness of our own; but in the strength of him, who is the Lord our Righteousness. The words of the church to Christ which follow, entreat an abiding place in his love, and protection by his power. Set me as a seal upon thine heart; let me always have a place in thine heart; let me have an impression of love upon thine heart. Of this the soul would be assured, and without a sense thereof no rest is to be found. Those who truly love Christ, are jealous of every thing that would draw them from him; especially of themselves, lest they should do any thing to provoke him to withdraw from them. If we love Christ, the fear of coming short of his love, or the temptations to forsake him, will be most painful to us. No waters can quench Christ's love to us, nor any floods drown it. Let nothing abate our love to him. Nor will life, and all its comforts, entice a believer from loving Christ. Love of Christ, will enable us to repel and triumph over temptations from the smiles of the world, as well as from its frowns.

seal—having her name and likeness engraven on it. His Holy Priesthood also in heaven (Ex 28:6-12, 15-30; Heb 4:14); "his heart" there answering to "thine heart" here, and "two shoulders" to "arm." (Compare Jer 22:24, with Hag 2:23). But the Holy Ghost (Eph 1:13, 14). As in So 8:5, she was "leaning" on Him, that is, her arm on His arm, her head on His bosom; so she prays now that before they part, her impression may be engraven both on His heart and His arm, answering to His love and His power (Ps 77:15; see Ge 38:18; Isa 62:3).
love is strong as death—(Ac 21:13; Ro 8:35-39; Re 12:11). This their love unto death flows from His (Joh 10:15; 15:13).
jealousy … the grave—Zealous love, jealous of all that would come between the soul and Jesus Christ (1Ki 19:10; Ps 106:30, 31; Lu 9:60; 14:26; 1Co 16:22).
cruel—rather, "unyielding" hard, as the grave will not let go those whom it once holds (Joh 10:28).
a most vehement flame—literally, "the fire-flame of Jehovah" (Ps 80:16; Isa 6:6). Nowhere else is God's name found in the Song. The zeal that burnt in Jesus Christ (Ps 69:9; Lu 12:49, 50) kindled in His followers (Ac 2:3; Ro 15:30; Php 2:17).
