Psalms 45:11

So shall the king greatly desire thy beauty: for he [is] thy Lord; and worship thou him.

Ver. 11. So shall the king greatly desire thy beauty] If thou deny thyself and forego all others to please him alone he shall set his whole heart upon thee, and be ravished with thy love, as Proverbs 5:19. How could that Persian lady's husband do less than love her, who, having been at Cyrus's wedding, and asked how she liked the bridegroom? Like him? said she, I know not how I like him; for I looked upon no man there but mine own husband. Aspasia Milesia was very dear to Cyrus, because she was καλη και σοφη, fair, and wise (Aelian).

For he is thy Lord] And, therefore, not to be slighted by thee for his great love, as many of the Persian monarchs were (Ahasuerus, for instance), but reverenced and obeyed, as Augustus was by his wife Livia.
