וַיִּקַּ֣ח יוֹסֵף֮ אֶת־שְׁנֵיהֶם֒ אֶת־אֶפְרַ֤יִם בִּֽימִינוֹ֙ מִשְּׂמֹ֣אל יִשְׂרָאֵ֔ל וְאֶת־מְנַשֶּׁ֥ה בִשְׂמֹאל֖וֹ מִימִ֣ין יִשְׂרָאֵ֑ל וַיַּגֵּ֖שׁ אֵלָֽיו׃
우수로는 에브라임을 이스라엘의 좌수를 향하게 하고 좌수로는 므낫세를 이스라엘의 우수를 향하게 하고 이끌어 그에게 가까이 나아가매
Rashi on Genesis
את אפרים בימינו משמאל ישראל EPHRAIM ON HIS RIGHT HAND TOWARDS ISRAEL’S LEFT — If one is moving towards another person his right hand is opposite the other’s left. Now since he (Manasseh) was the first-born he was marked out for the blessing and should have been placed at Jacob’s right hand.
Rashbam on Genesis
את אפרים בימינו, in order to place him on Israel’s left side, (seeing he was the younger).
Radak on Genesis
בימינו, on Joseph’s right, which was the left side of Yaakov (Yisrael)
