The king’s daughter - This evidently refers to the bride, the daughter of the foreign king. The verse contains a description of her beauty - her splendor of attire - before she is brought to the king, her future husband. She is represented here as in the palace or home of her father, before she is conducted forth to be given to her future husband in marriage. Is all “glorious.” Is all splendor or beauty; is altogether splendor. There is nothing that is not splendid, rich, magnificent in her appearance, or in her apparel. As seen in Psalms 45:9, she is clad in gold; she is surrounded by honorable women - the daughters of kings Psalms 45:9, and encompassed with the rich, Psalms 45:12. As seen here, she is in her father’s house, adorned for the marriage, and to be brought to the king, her future husband, attired in all that could give grace and beauty to her person. The allusion here, as referring to the church - the “bride of the Lamb” - “may be” to that church considered as redeemed, and about to be received to heaven, to dwell with its Husband and Saviour. Compare the notes at Revelation 19:7-8; notes at Revelation 21:2, notes at Revelation 21:9.
Within - This does not refer to herself, as if she was not merely splendid in her attire, but holy and pure - glorious and lovely - in “heart;” it refers to her as seen while yet “within” the palace or home of her father, in her own dwelling. The Hebrew word - פנימה penı̂ymâh - means properly, “at or by the inner wall of a house, room, or court; that is, opposite to or in front of the door, and of those entering.” Gesenius, “Lexicon” As seen in her dwelling - within the palace - in the most honored place - she is arrayed in gorgeous apparel, and adorned as becomes a king’s daughter about to be married.
Her clothing is of wrought gold - Gold embroidery. See Psalms 45:9. That is, she is arrayed in the richest apparel.
