There are threescore queens - Though there be sixty queens, and eighty concubines, or secondary wives, and virgins innumerable, in my harem, yet thou, my dove, my undefiled, art אצת achath, One, the Only One, she in whom I delight beyond all.

There are (d) sixty queens, and eighty concubines, and virgins without number.
(d) Meaning that the gifts are infinite which Christ gives to his Church: or that his faithful are many in number.

There are threescore queens, and fourscore concubines, and virgins without number. In this verse and Song 6:9 the church is commended as she stood related to others; and is compared with them, and preferred to them. The words may be considered either as an assertion, "there are", &c. or as a supposition, "though there be", &c. yet Christ's church is but one, and excels them all. "Queens" are principal and lawful wives of kings; "concubines", secondary or half wives, as the word (i) signifies; who were admitted to the bed, but their children did not inherit: "virgins", unmarried persons, maids of honour, who waited on the queen. The allusion is to the custom of kings and great personages, who had many wives, and more concubines, and a large number of virgins to wait on them; see 1-Kings 11:3; or to a nuptial solemnity, and the ceremony of introducing the bride to the bridegroom, attended with a large number of persons of distinction; and so Theocritus (k) speaks of four times sixty virgins attending the nuptials of Menelaus and Helena; see Psalm 45:9. By all which may be meant either the kingdoms and nations of the world; by "queens", the more large, rich and flourishing kingdoms; by "concubines", inferior states; and by "virgins without number", the vast multitudes of inhabitants that fill them; but all, put together, are not equal to the church; see Song 2:2; or else false churches; by "queens", such who boast of their riches and number, as the church of Rome, Revelation 18:7; by "concubines", such as are inferior in those things, but equally corrupt, as Arians, Socinians, &c. and by "virgins without number", the multitudes of poor, weak, ignorant people, seduced by them; and what figure soever these make, or pretensions to be the true churches of Christ, they are none of his, his spouse is preferred to them all. Or rather true believers in Christ, of different degrees, are here meant; queens, those that have the greatest share of gifts grace, most nearness to Christ, and communion with him; by "concubines", believers of a lower class, and of a more servile spirit, and yet sometimes are favoured with, fellowship with Christ; and by "virgins", young converts, who have not so large an experience as the former; and this distribution agrees with 1-John 2:13; and the rather this may be the sense, since each of these are said to praise the church in Song 6:9, who is preferable to them, and includes them all.
(i) "secundariae uxores", Michaelis. (k) Idyll. 18. v. 24.

threescore--indefinite number, as in Song 3:7. Not queens, &c., of Solomon, but witnesses of the espousals, rulers of the earth contrasted with the saints, who, though many, are but "one" bride (Isaiah 52:15; Luke 22:25-26; John 17:21; 1-Corinthians 10:17). The one Bride is contrasted with the many wives whom Eastern kings had in violation of the marriage law (1-Kings 11:1-3).

8 There are sixty queens,
And eighty concubines,
And virgins without number.
9 One is my dove, my perfect one, -
The only one of her mother,
The choice one of her that bare her.
The daughters saw her and called her blessed, -
Queens and concubines, and they extolled her.
Even here, where, if anywhere, notice of the difference of gender was to be expected, המּה stands instead of the more accurate הנּה (e.g., Genesis 6:2). The number off the women of Solomon's court, 1-Kings 11:3, is far greater (700 wives and 300 concubines); and those who deny the Solomonic authorship of the Song regard the poet, in this particular, as more historical than the historian. On our part, holding as we do the Solomonic authorship of the book, we conclude from these low numbers that the Song celebrates a love-relation of Solomon's at the commencement of his reign: his luxury had not then reached the enormous height to which he, the same Solomon, looks back, and which he designates, Ecclesiastes 2:8, as vanitas vanitatum. At any rate, the number of 60 מלכות, i.e., legitimate wives of equal rank with himself, is yet high enough; for, according to 2-Chronicles 11:21, Rehoboam had 18 wives and 60 concubines. The 60 occurred before, at Song 3:7. If it be a round number, as sometimes, although rarely, sexaginta is thus used (Hitzig), it may be reduced only to 51, but not further, especially here, where 80 stands along with it. פילגשׁ (פּלּגשׁ), Gr. πάλλαξ παλλακή (Lat. pellex), which in the form פּלּקתּא (פּלקתא) came back from the Greek to the Aramaic, is a word as yet unexplained. According to the formation, it may be compared to חרמשׁ, from חרם, to cut off; whence also the harem bears the (Arab.) name ḥaram, or the separated synaeconitis, to which access is denied. And ending in is (ש) is known to the Assyr., but only as an adverbial ending, which, as 'istinis = לבדּו, alone, solus, shows is connected with the pron. su. These two nouns appear as thus requiring to be referred to quadrilitera, with the annexed שׁ; perhaps פלגשׁ, in the sense of to break into splinters, from פּלג, to divide (whence a brook, as dividing itself in its channels, has the name of פּלג), points to the polygamous relation as a breaking up of the marriage of one; so that a concubine has the name pillěgěsh, as a representant of polygamy in contrast to monogamy.
In the first line of Song 6:9 אחת is subj. (one, who is my dove, my perfect one); in the second line, on the contrary, it is pred. (one, unica, is she of her mother). That Shulamith was her mother's only child does not, however, follow from this; אחת, unica, is equivalent to unice dilecta, as יחיד, Proverbs 4:3, is equivalent to unice dilectus (cf. Keil's Zac 14:7). The parall. בּרה has its nearest signification electa (lxx, Syr., Jerome), not pura (Venet.); the fundamental idea of cutting and separating divides itself into the ideas of choosing and purifying. The Aorists, Song 6:9, are the only ones in this book; they denote that Shulamith's look had, on the part of the women, this immediate result, that they willingly assigned to her the good fortune of being preferred to them all, - that to her the prize was due. The words, as also at Proverbs 31:28, are an echo of Genesis 30:13, - the books of the Chokma delight in references to Genesis, the book of pre-Israelitish origin. Here, in Song 6:8, Song 6:9, the distinction between our typical and the allegorical interpretation is correctly seen. The latter is bound to explain what the 60 and the 80 mean, and how the wives, concubines, and "virgins" of the harem are to be distinguished from each other; but what till now has been attempted in this matter has, by reason of its very absurdity or folly, become an easy subject of wanton mockery. But the typical interpretation regards the 60 and the 80, and the unreckoned number, as what their names denote, - viz. favourites, concubines, and serving-maids. But to see an allegory of heavenly things in such a herd of women - a kind of thing which the Book of Genesis dates from the degradation of marriage in the line of Cain - is a profanation of that which is holy. The fact is, that by a violation of the law of God (Deuteronomy 17:17), Solomon brings a cloud over the typical representation, which is not at all to be thought of in connection with the Antitype. Solomon, as Jul Sturm rightly remarks, is not to be considered by himself, but only in his relation to Shulamith. In Christ, on the contrary, is no imperfection; sin remains in the congregation. In the Song, the bride is purer than the bridegroom; but in the fulfilling of the Song this relation is reversed: the bridegroom is purer than the bride.

Threescore - A certain number for an uncertain. The sense seems to be this, there are many beautiful queens and concubines in the world, in the courts of princes, but none of them is to be compared with my spouse.
