Deuteronomy 33:16

ורצון שכני סנה — the last two words are the equivalent of שוכן סנה (the י being the suffix that that sometimes appears in participles, for the most part in poetry). The-meaning is: And may his land further be blessed through the favour (רצון) and satisfaction of the Holy One, blessed be He, who first revealed himself to me in the thorn-bush (סנה‎). רצון means satisfaction and appeasement, and similar is the meaning wherever רצון occurs in scripture. תבואתה LET IT COME — i.e. let this blessing come לראש יוסף ON JOSEPH'S HEAD. נזיר אחיו means THE ONE WHO WAS SEPARATED FROM HIS BRETHREN through his being sold.

וּמִמֶּ֗גֶד אֶ֚רֶץ וּמְלֹאָ֔הּ וּרְצ֥וֹן שֹׁכְנִ֖י סְנֶ֑ה תָּב֙וֹאתָה֙ לְרֹ֣אשׁ יוֹסֵ֔ף וּלְקׇדְקֹ֖ד נְזִ֥יר אֶחָֽיו׃

and for the precious things of the earth and its fulness, and for the good will of him that dwelt in the bush: let the blessing come upon the head of Yosef, and upon the top of the head of him who was separated from his brothers.
