מדרש אויף איוב 38:35

4) Above Vilon, Raqia', and in Raqia' there are stars and constellations and twelve windows corresponding to the twelve hours, and 365 angels watch over the sun and bring it proudly from window to window, so that the universe not turn around in a single hour, and in these windows they bring the moon proudly at night, and as it comes out they open and say a song, and they are not silent until the sun sets, and when the sun sets in the west they bow and say "We did all that You commanded us!" As it is said, "Can you send lightning and it goes, saying to you 'Here we are!'?" (Job 38:35). Why are the sun and moon and stars and constellations in Raqia'? As it is written, "And God put them in the firmament¹raqia' of the heavens, to illuminate over the earth." (Genesis 1:17)

(Exodus 12:1) "saying": Go and say it to them immediately. These are the words of R. Yishmael. As it is written (Exodus 34:34) "And he went out and spoke to the children of Israel what he had been commanded." R. Eliezer says: (The intent is) Go out and say it to them and return word to Me, viz. (Ibid. 19:8) "and Moses returned the words of the people to the L–rd," and (Ezekiel 9:11) "And, behold, the man clothed in linen on whose loins was the scribe's slate returned word saying I have done according to all that You have commanded me," and (Iyyov 38:35) "Did you dispatch lightning bolts, so that they should go forth and say to you 'Here we are'"? The messengers of the Holy One Blessed be He are not as those of flesh and blood. The messengers of flesh and blood must return to their sender. Not so Your messengers, but "Did You dispatch lightning bolts so that they should go forth?" It is not written "and they shall return and say." Wherever they go they are before You and they say we have fulfilled Your embassy, in fulfillment of (Jeremiah 23:24) "Do I not fill the heavens and the earth?"

(Fol. 25) R. Joshua b. Levi said: "We must be grateful to our forefathers for having informed us of the place where we are to pray; as it is said (Nech. 9, 6) And the host of the heavens, the sun and all other illuminaries which are in the east bow down before Thee towards the West." R. Akiba b. Jacob opposed it, saying: "Perhaps they go backwards, as a slave does usually before his master; and when they come to the West, they bow toward the East?" The objection remains. R. Hoshia, however, holds that the Shechina is all over, for R. Hoshia said: "Whence do we learn that the Shechina is all over? It is said (Ib., ib.) Thou indeed art the Eternal One alone; i.e.. Thy messengers are not like the messengers of frail man; for the messenger of frail man usually returns [when he has accomplished his task] to the place from which he was sent [announcing the fulfillment of his duty], but Thy messengers report the fulfillment of duty at the very place to which they were sent; as it is said (Job, 38, 35) Canst thou send out lightnings that may go, and say unto thee, "Here are we." It does not read that they come and say Here are we, but that they go and say it in the place to which they were sent. Hence the Shechina is all over." And R. Ishmael also maintains the same; for at the school of R. Ishmael it was taught, whence do we learn that the Shechina is all over? It is said (Zeeh. 2, 7) And behold, the angel that spoke with me went out, and another angel eame out to meet him. It does not read after him (achrar), but against him (likrath); infer from this that the Shechina is everywhere. And R. Shesheth also agrees with his interpretation, for R. Shesheth [who was blind] would say to his servant: "You may place me [for prayer] in any direction except due East: not because the Shechina is not resting there, but because the minim have decided that one must pray only towards due East." R. Abahu, however, maintains that the Shechina is resting in the West; for R. Abahu said: "Why is the West called Uriya? Because the Divine air is there."
