פירוש על הושע 5:3

for now you have committed harlotry, O Ephraim Until Hosea son of Elah, they blamed their sins on their kings, who prevented them from going on the pilgrimages. This one arose and abolished the sentries; yet they did not go up. Therefore, they were exiled. For now you have committed harlotry, O Ephraim, and they cannot blame the king. I learned this in Seder Olam (ch. 22).
