פירוש על עמוס 8:10

And I will turn your festivals into mourning—as the matter is stated: (II Chron 35:24) “And all Judah and Jerusalem mourned for Josiah.”

and all your songs into lamentation—as the matter is stated: (ibid. verse 25) “And all the singing men and singing women spoke in their lamentations.”

like the mourning for an only son—Like a father who mourns over an only son.
