פירוש על עבודה זרה 47:15

The other sages responded to R. Eliezer with a verse from Isaiah. According to this verse, in the future, all the flocks of Kedar, a land inhabited by non-Jews, will be brought to the Temple to be sacrifices. This proves that non-Jews can bring sacrifices. R. Eliezer responds that in the future these nations will convert. This verse is thus not proof of non-Jews bringing sacrifices.
