וַיְבָ֨רֲכֵ֜ם בַּיּ֣וֹם הַהוּא֮ לֵאמוֹר֒ בְּךָ֗ יְבָרֵ֤ךְ יִשְׂרָאֵל֙ לֵאמֹ֔ר יְשִֽׂמְךָ֣ אֱלֹהִ֔ים כְּאֶפְרַ֖יִם וְכִמְנַשֶּׁ֑ה וַיָּ֥שֶׂם אֶת־אֶפְרַ֖יִם לִפְנֵ֥י מְנַשֶּֽׁה׃
그 날에 그들에게 축복하여 가로되 이스라엘 족속이 너로 축복하기를 하나님이 너로 에브라임 같고 므낫세 같게 하시리라 하리라 하여 에브라임을 므낫세보다 앞세웠더라
Rashi on Genesis
בך יברך ישראל IN THEE SHALL ISRAEL BLESS — When one wishes to bless his sons he will bless them by reciting the formula with which they were blessed — a man will say to his son, “God make thee as Ephraim and as Manasseh.”
Ramban on Genesis
AND HE BLESSED THEM THAT DAY. The meaning of that day is that since Joseph had urged him to give Menasheh precedence, the verse declares that Jacob did not wish to remove his right hand from Ephraim’s head to that of Menasheh. Moreover, he expressly reiterated on that occasion, in Joseph’s presence, when he blessed them by saying, As Ephraim and Menasheh. And he put Ephraim before Menasheh in all his blessings.
