וְנִסְלַ֗ח לְכָל־עֲדַת֙ בְּנֵ֣י יִשְׂרָאֵ֔ל וְלַגֵּ֖ר הַגָּ֣ר בְּתוֹכָ֑ם כִּ֥י לְכָל־הָעָ֖ם בִּשְׁגָגָֽה׃ (ס)
Seluruh jemaah bani Israel akan diampuni, demikian pula pendatang yang tinggal di tengah-tengah mereka, sebab hal itu terjadi atas seluruh bangsa karena kekeliruan tanpa sengaja.
Ramban
AND THE STRANGER THAT SOJOURNETH AMONG THEM. He mentioned “the stranger” because they are always more liable to stumble in this sin [of idolatry] and thereby to cause Israel to stumble [with them].
Tur HaArokh
The Torah also mentions the גר, the stranger, (proselyte) separately, as due to their only recently having converted they are more likely to commit sins erroneously. 15,31 עונה בה, “his sin is upon him.” According to the plain meaning of the text the meaning of this expression is similar to such an expression as דמיהם בם. (Leviticus 20,11, at al) their “blood-guilt” will remain upon them (as long as they have not repented). Another similar expression is ערירים ימותו עונם ישאו, “they will die childless while bearing the burden of their guilt.” (Compare Leviticus 20,20)
Rav Hirsch
V. 26. Dass hier bei כפרה für שגגת ע׳׳ז der גר הגר בתוכם insbesondere als der סליחה gewürdigt hervorgehoben wird, dürfte vielleicht darin das Motiv haben, daß eben bei einem aus dem Heidentum Eingetretenen eine Abirrung zu ע׳׳ז ernster als Rückfall zu fassen scheinen könnte. כי לכל העם בשגגה, die Gesetzübertretung ist dem ganzen Volke durch eine Verirrung zugekommen.
