His banner - As the standard is the rallying-point and guide of the individual soldier, so the bride, transplanted from a lowly station to new scenes of unaccustomed splendor, finds support and safety in the known attachment of her beloved. His "love" is her "banner." The thought is similar to that expressed in the name "Jehovah-nissi" (see the Exodus 17:15 note).

He brought me to the banqueting house - Literally, the house of wine. The ancients preserved their wine, not in barrels or dark cellars under ground, as we do, but in large pitchers, ranged against the wall in some upper apartment in the house, the place where they kept their most precious effects. We have a proof of this in Homer: -
Ως φαν· ὁ δ' ὑψοραφον θαλομον κατεβησατο πατρος
Ευρυν, ὁθι νητος χρυσος και χαλκος εκειτο,
Εσθης τ' εν χηλοισιν, ἁλις τ' ευωδες ελαιον.
Εν δε πιθοι οινοιο παλαιου ἡδυποτοιο
Εστασαν, ακρητον θειον ποτον εντος εχοντες,
Ἑξειης ποτε τοιχον αρηροτες· ειποτ' Οδυσσευς
Οικαδε νοστησειε, και αλγεα πολλα μογησας.
Κληΐσται δ' επεσαν σανιδες πυκινως αραρυιαι,
Δικλιδες· εν δε γυνη ταμιη νυκτας τε και ημαρ
Εσχ', κ. τ. λ.. Od. lib. ii., ver. 337.
Meantime the lofty rooms the prince surveys,
Where lay the treasures of th' Ithacian race.
Here, ruddy brass and gold refulgent blazed;
There, polished chests embroider'd gestures graced.
Here, pots of oil breathed forth a rich perfume;
There, jars of wine in rows adorn'd the dome.
(Pure flavorous wine, by gods in bounty given,
And worthy to exalt the feasts of heaven).
Untouch'd they stood, till, his long labors o'er,
The great Ulysses reach'd his native shore.
A double strength of bars secured the gates;
Fast by the door wise Euryclea waits, etc.
Pope.

He brought me to the banqueting house,.... Or "into" it (q). The "house of wine" (r), as it is literally in the original; either the "wine cellar" (s), as some, where stores of it were kept; or, the "place of fasting" (t), as others, and, as we render it, a "banqueting house"; where it was distributed and drank; a banquet of wine being put for a feast, and here the nuptial feast; and may design the Gospel feast in the house of God, where there is plenty of the wine of Gospel truths, and provisions of rich food, with which believers are sweetly refreshed and delightfully regaled: and to be brought hither, under the drawings and influences of divine grace, is a special privilege, a distinguishing layout; and show a great condescension in Christ, the King of kings, and Lord of lords, to take his people by the hand, as it were, and introduce them into his house, so well furnished, and to a table so well spread: and so the church relates it as an instance of divine favour, and as a fresh token of Christ's love to her; which further appears by what follows: the covenant of grace and the Scriptures of truth may be thought of as a banqueting house, well stored with blessings, and promises, and rich provisions; which, to be led and let into, is a singular kindness;
and his banner over me was love; signifying, that she was brought into the banqueting house in a grand, stately, and majestic manner, with flying colours; the motto on which inscribed was "love"; the allusion may be to the names of generals being inscribed on the banners of their armies; so Vespasian's name was inscribed on the banners throughout his armies (u). Christ's name, inscribed on his, was "love", his church's love; and by which his company or band was distinguished from all others, even by electing, redeeming, calling love. It may signify the security and protection of the saints, while in the house of God, and enjoying communion with him, being under the banner of love, with which they are encompassed as a shield; and it may denote the very manifest and visible displays of it, which the church now experienced.

Historically fulfilled in the joy of Simeon and Anna in the temple, over the infant Saviour (Luke 2:25-38), and that of Mary, too (compare Luke 1:53); typified (Exodus 24:9-11). Spiritually, the bride or beloved is led (Song 2:4) first into the King's chambers, thence is drawn after Him in answer to her prayer; is next received on a grassy couch under a cedar kiosk; and at last in a "banqueting hall," such as, JOSEPHUS says, Solomon had in his palace, "wherein all the vessels were of gold" (Antiquities, 8:5,2). The transition is from holy retirement to public ordinances, church worship, and the Lord's Supper (Psalm 36:8). The bride, as the queen of Sheba, is given "all her desire" (1-Kings 10:13; Psalm 63:5; Ephesians 3:8, Ephesians 3:16-21; Philippians 4:19); type of the heavenly feast hereafter (Isaiah 25:6, Isaiah 25:9).
his banner . . . love--After having rescued us from the enemy, our victorious captain (Hebrews 2:10) seats us at the banquet under a banner inscribed with His name, "love" (1-John 4:8). His love conquered us to Himself; this banner rallies round us the forces of Omnipotence, as our protection; it marks to what country we belong, heaven, the abode of love, and in what we most glory, the cross of Jesus Christ, through which we triumph (Romans 8:37; 1-Corinthians 15:57; Revelation 3:21). Compare with "over me," "underneath are the everlasting arms" (Deuteronomy 33:27).

4 He has brought me into the wine-house,
And his banner over me is love.
After we have seen the ladies of the palace at the feast, in which wine is presented, and after Solomon, till now absent, has entered the banqueting-chamber (Arab. meglis), by היּין בּית we are not to understand the vineyard, which would be called bēth hǎggephānim or bēth hā'ǎnāvim, as in Acts 1:12, Pesh. the Mount of Olives, bēth zaite.
(Note: In Hebrews. יין does not denote the vine as a plant, as the Aethiop. wain, whence asada wain, wine-court = vineyard, which Ewald compares; Dillmann, however, ineptly cites "vine-arbour," and South-Germ. "kamerte" = vinea camerata; in Hebrews. היין בּית is the house in which wine is drunk.)
He has introduced her to the place where he royally entertains his friends. Well knowing that she, the poor and sunburnt maiden, does not properly belong to such a place, and would rather escape away from it, he relieves her from her fear and bashfulness, for he covers her with his fear-inspiring, awful, and thus surely protecting, banner; and this banner, which he waves over her, and under which she is well concealed, is "love." דּגל (from דּגל, to cover) is the name of the covering of the shaft or standard, i.e., pannus, the piece of cloth fastened to a shaft. Like a pennon, the love of the king hovers over her; and so powerful, so surpassing, is the delight of this love which pervades and transports her, that she cries out:

Banquetting house - The places in which believers receive the graces and blessings of Christ. His banner - By the lifting up whereof I was invited to come to him, and to list myself under him. Love - The love of Christ crucified, which, like a banner, is displayed in the gospel.
