בִּרְכֹ֣ת אָבִ֗יךָ גָּֽבְרוּ֙ עַל־בִּרְכֹ֣ת הוֹרַ֔י עַֽד־תַּאֲוַ֖ת גִּבְעֹ֣ת עוֹלָ֑ם תִּֽהְיֶ֙ין֙ לְרֹ֣אשׁ יוֹסֵ֔ף וּלְקָדְקֹ֖ד נְזִ֥יר אֶחָֽיו׃ (פ)
Благословения отца твоего Могущественны за пределами благословений моих прародителей До предела вечных холмов; Они будут на голове Иосифа и на макушке головы князя среди братьев его.
Rashi
'ברכת אביך גברו וגו THE BLESSING OF THY FATHER HAVE PREVAILED etc. — The blessings which the Holy One, blessed be He, bestowed upon me are mighty beyond the blessings wherewith He blessed my progenitors

נזיר אחיו, “the one who had been separated from his brothers.” Our author understands the word נזיר here as “the prince among his brothers.” He uses Lamentations 4,7, זכו נזיריה משלג, “her elect were purer than snow, ”as the source where the word is used in that context.
Da'at Zekenim
עד תאות גבעות עולם, “as far as the hills at the end of the world;” according to Rashi, Yaakov was able to extend such blessings as a reward for having fed his father with the delicacies that he used to enjoy. G–d had already enlarged the scope of his blessings to him when He told him that his descendants would spread in all directions of the globe. (Genesis 28,14)
