וְגִבַּרְתִּ֣י ׀ אֶת־בֵּ֣ית יְהוּדָ֗ה וְאֶת־בֵּ֤ית יוֹסֵף֙ אוֹשִׁ֔יעַ וְהֽוֹשְׁבוֹתִים֙ כִּ֣י רִֽחַמְתִּ֔ים וְהָי֖וּ כַּאֲשֶׁ֣ר לֹֽא־זְנַחְתִּ֑ים כִּ֗י אֲנִ֛י יְהוָ֥ה אֱלֹהֵיהֶ֖ם וְאֶעֱנֵֽם׃
내가 유다 족속을 견고하게 하며 요셉 족속을 구원할지라 내가 그들을 긍휼히 여김으로 그들로 돌아오게 하리니 그들이 내게 내어 버리움이 없었음 같이 되리라 나는 그들의 하나님 여호와라 내가 그들을 들으리라
Ramban
AND LET MY NAME BE CALLED ON THEM. Rabbi Abraham ibn Ezra said that it means that all Israel be called by the name Ephraim,57As in the verse: Is Ephraim a darling son unto me? (Jeremiah 31:19), the reference there being to all Israel. just as they are called “the children of Abraham, Isaac, and Jacob.”
This is not correct for Scripture uses the word bahem (on them), [thus referring to both Ephraim and Menasheh], and they were not called by the name of Menasheh. But perhaps this is because they were called the house of Joseph.58Zechariah 10:6. And I will help the house of Joseph.
The correct interpretation though is that their race and their name will exist forever, and the name of Abraham, Isaac and Jacob will forever be upon them.
