Albert Barnes Commentary Psalms 45:13

"The king`s daughter within [the palace] is all glorious: Her clothing is inwrought with gold." — Psalms 45:13 (ASV)

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 led out to be given to her future husband in marriage. She is all glorious. She is all splendor or beauty; she is altogether splendor.

There is nothing that is not splendid, rich, magnificent in her appearance or in her apparel. As seen in Psalm 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, referring to the church — the bride of the Lamb — “may be” to that church considered as redeemed and about to be received into heaven to dwell with its Husband and Saviour. (see also Revelation 21:2 and 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 still within the palace or home of her father, in her own dwelling. The Hebrew word, פנימה (peniymâh), 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 befits a king’s daughter about to be married.

Her clothing is of wrought gold - Gold embroidery. . That is, she is arrayed in the richest apparel.
