Musar do Psalmów 72:16

I believe there is a profound reason why the formula chosen is one that can refer to either the future or the past. We bless the sacred bread of the past which Adam ate before the sin, and which will once again be available in the future. We have a similar discussion between Rabbi Nechemiah and the sages quoted in Shemot Rabbah, 15 where the sages quote Psalms 72,16 to prove that the word המוציא also refers to the future. The Psalmist says: יהי פסת בר בארץ, "Let abundant grain (in the shape of a piece of bread) be on earth."
