The Queen of Sheba came to Solomon from the ends of the earth, from the periphery, to question him of wisdom, to which he provided every answer to her satisfaction, but for her life and love remained directed towards the Chief Architect -for Hiram Abif! and of the science and word by which the temple may be built, and so with the wisdom of the starry world the path is sought, in time and space, as our soul also descends into the depths of matter: – For she is "dark but comely". 

Why Hiram and not Solomon?

The answer: Solomon's wisdom was old - as he said, Wisdom increased suffering! The Queen wanted excitement and joy! The work was certainly not done! Even if Jehovah had said: My work is 'completed', for her it was not! And so she needed a Co-Creator, and that was one that could comprehend her soul, and that was the gift of love that streamed between them. It is human: and God said to Eve in the Garden: 'it will take a long time', and so it did take a long time - and we are the children, all of us are the children of the 'long-time'.
