Musar על ברכות 115:16

We find that Moses was most insistent that G–d personally proclaim who would look after Israel's temporal needs; the Torah quotes Moses as using strong language in this regard in Numbers 27,15. Moses' request is introduced with the most unusual wording: וידבר משה אל ה' לאמור, Both the word וידבר, and the word לאמור are unusual. To whom did Moses expect G–d to relay his words? The Ari zal suggests that Moses was adamant that all the various layers of the heavens be informed who Israel's פרנס, economic leader would be.
