דֶּ֣גֶל מַחֲנֵ֥ה אֶפְרַ֛יִם לְצִבְאֹתָ֖ם יָ֑מָּה וְנָשִׂיא֙ לִבְנֵ֣י אֶפְרַ֔יִם אֱלִישָׁמָ֖ע בֶּן־עַמִּיהֽוּד׃
서편에는 에브라임의 군대의 진 기가 있을 것이라 에브라임 자손의 족장은 암미훗의 아들 엘리사마요
Rashi
וישם את אפרים AND HE PUT EPHRAIM etc. — i.e. in the blessing he bestowed upon them he put Ephraim’s name before that of Manasseh, so giving him precedence over his brother when the Israelites encamped and marched beneath their banners in the wilderness (cf. Numbers 2:18 and Numbers 10:22), and when at the dedication of the altar by the princes of the tribes each brought his gifts (cf. Numbers 7:48 Numbers 7:54). (see Genesis Rabbah 97:5).
