Matthew Poole and continuators on Genesis 49:26

26 The blessings of thy father have prevailed above the blessings of my progenitors ; unto the utmost bound of the everlasting hills , they shall be on the head of Joseph, and on the crown of the head of him that was separate from his brethren .

The blessings which I thy Father have conferred upon thee are much more considerable than those which I received from my father Isaac or from my grandfather Abraham.

These words seem to note the duration of Josephs blessing, that it should continue even to the bounds of the everlasting or lasting or antient hills, i. e. as long as the most solid and stable mountains shall last, i. e. for ever. Perpetuity is described by the continuance of the Mountains, as Isa. 54. 10. or of the Sun and Moon, as Psal. 72. 5, 7, 17. or of the heavens and earth, as Mat. 5. 18. In the foregoing words of this verse he commends these blessings from their excellency above all former blessings, and here he commends them from their durableness.

Or, let them be. For this may be a prayer to God that these blessings may be constant and perpetual.

So he was, when he was sold into Egypt, and abode there in the court when his brethren were in Goshen, or, the crowned of or among his brethren, i. e. who, though he was once scorned and trampled upon by his brethren, yet now is highly honoured and advanced above them. Others, the Nazarite of or among his brethren, as he may be called either for his purity and sanctity, or for his eminency and dignity. But we must remember that the Nazarites were as yet unknown, being instituted long after this time.
