Jamieson, Fausset and Brown on Song of Solomon 3:6

6. New scene (So 3:6-11). The friends of the Bridegroom see a cortege approach. His palanquin and guard.

cometh out--rather, "up from"; the wilderness was lower than Jerusalem [Maurer].

pillars of smoke--from the perfumes burned around Him and His bride. Image from Israel and the tabernacle (answering to "bed," So 3:7) marching through the desert with the pillar of smoke by day and fire by night (Ex 14:20), and the pillars of smoke ascending from the altars of incense and of atonement; so Jesus Christ's righteousness, atonement, and ever-living intercession. Balaam, the last representative of patriarchism, was required to curse the Jewish Church, just as it afterwards would not succumb to Christianity without a struggle (Nu 22:41), but he had to bless in language like that here (Nu 24:5, 6). Angels too joyfully ask the same question, when Jesus Christ with the tabernacle of His body (answering to "His bed," So 3:7; Joh 1:14, "dwelt," Greek "tabernacled," Joh 2:21) ascends into heaven (Psa 24:8-10); also when they see His glorious bride with Him (Psa 68:18; Re 7:13-17). Encouragement to her; amid the darkest trials (So 3:1), she is still on the road to glory (So 3:11) in a palanquin "paved with love" (So 3:10); she is now in soul spiritually "coming," exhaling the sweet graces, faith, love, joy, peace, prayer, and praise; (the fire is lighted within, the "smoke" is seen without, Ac 4:13); it is in the desert of trial (So 3:1-3) she gets them; she is the "merchant" buying from Jesus Christ without money or price (Is 55:1; Re 3:18); just as myrrh and frankincense are got, not in Egypt, but in the Arabian sands and the mountains of Palestine. Hereafter she shall "come" (So 3:6, 11) in a glorified body, too (Php 3:21). Historically, Jesus Christ returning from the wilderness, full of the Holy Ghost (Lu 4:1, 14). The same, "Who is this," &c. (Is 63:1, 5).
