זוהר בראשית — דף רנ ע”א

From the mountains where the force of the sun shines, the dust of the earth produces gold, and were it not for wild beasts there would be no poor people. In Solomon's days silver was worth nothing because the force of the sun gazed upon dust and multiplied gold. Solomon received wisdom from the mother's side and merited that the sun was directed toward him. The sun is the masculine, Judgment is what hardens and gold multiplies from there. Solomon was attached to three Names: Wisdom, Understanding and Knowledge, and by virtue of this he ruled over all worlds.
