Variantly: "And this is the blessing": This is what he (Moses) added to the first blessing, whereby they were blessed by Jacob his father, viz. (Bereshith 49:28) "And this is what their father spoke to them and blessed them." We find, then, that from the place where our father Jacob concluded blessing his sons — from that place, Moses began to bless them, viz. "And this is the blessing." Variantly: "And this is the blessing": This adds to a previous (blessing). And which is that? (Psalms 90:1) "A prayer of Moses, the man of G-d." And we still do not know whether the prayer preceded the blessing or the blessing preceded the prayer. "And this is the blessing" indicates that the prayer preceded the blessing and not that the blessing preceded the prayer.
