George Foot Moore, The Literature of the Old Testament
“ The doom which Amos sees impending over Israel is visited upon it in retribution for the wrongs which men inflict upon their fellows, the oppression of the poor by the rich, the small man by the great; the injustice, often in the forms of law, by which men are deprived of property and liberty; the luxury, aping foreign modes, which is not only corrupting in itself, but is the chief motive of injustice and oppression and fraud. The very prosperity of the nation was its ruin. ”
