זוהר שמות — דף רלג ע”א

When the sun hides its face from the moon, she is in poverty and darkness; when it shines upon her, she adorns herself like the female toward the male and reigns. David reflected this by saying I am young and despised and also your commandments I have not forgotten. Ezekiel saw a man of copper appearance with a measuring reed — he is a messenger of the left side who changes his garments according to his mission. The measuring reed emerges from the hidden spark, and the measure below derives from the measure above, like the cubit measurement of the Tabernacle.
