Rabbi Shimon rose and said: Enter, holy hosts of above and of below, to witness the adornments of the bride. For the wedding canopy is decorated for Her, and the groom is waiting there for Her. He said: Elijah! Elijah! Descend to us, you and the hosts of souls of the righteous from the schools of above and of below, in order to adorn the bride. Immediately, Elijah descended, along with many angelic hosts and many souls.
When the groom, that is, the sun, comes to light up the moon, she decorates her hair with thirteen decorations - twelve constellations and the moon. And He (Psalms 19:6) "is like a groom coming forth from his chamber; like a hero, eager (yasis) to run," - to run his courses in the heavens. He surely peeks (yatsits) at her, as it says (Song of Songs 2:9) "Peeking through the lattice." - looking at her in the heavens.
