Deuteronomy 33:16

And for the precious things of the earth and fulness thereof, and for the good will of him that dwelt in the bush: let the blessing come upon the head of Joseph, and upon the top of the head of him that was separated from his brethren.

For the good will of him that dwelt in the bush - i:e., every blessing that may be expected from the kindness of God, who formerly appeared to me in the bush, in order to manifest His interest in the emancipation and permanent prosperity of His people (see the note at Exodus 3:2).

Let the blessing come upon the head of Joseph ... - (see, for an explanation of this last clause, the note at Genesis 49:26.)
