What is thy beloved more than another beloved - This question gives the bride an opportunity to break out into a highly wrought description of the beauty and perfections of her spouse.
Matthew Henry
Concise Bible Commentary
Even those who have little acquaintance with Christ, cannot but see amiable beauty in others who bear his image. There are hopes of those who begin to inquire concerning Christ and his perfections. Christians, who are well acquainted with Christ themselves, should do all they can to make others know something of him. Divine glory makes him truly lovely in the eyes of all who are enlightened to discern spiritual things. He is white in the spotless innocence of his life, ruddy in the bleeding sufferings he went through at his death. This description of the person of the Beloved, would form, in the figurative language of those times, a portrait of beauty of person and of grace of manners; but the aptness of some of the allusions may not appear to us. He shall come to be glorified in his saints, and to be admired in all that believe. May his love constrain us to live to his glory.

Volume 1-7
10. Chiefest among ten thousand. A fitting title of Christ (see DA 827; MB 79, 100; COL 339).
The description of the bridegroom continues through v.16 and reaches a climax in the expression “He is altogether lovely.” This description is frequently coupled with the title, “chiefest among ten thousand,” when referring to Christ (see in addition to the above references, Ed 69; 6T 175; CT 67).
