Social injustice and the OT Prophet

“…injustice is sin against God, and no consequences, however deplorable from the manward point of view, could equal the terrible significance of the religious fact to the prophetic consciousness. In short, it is not the circumstance that the rich injure the poor from which the prophetic mind in the first instance revolts, but what shocks and excites the prophets’ resentment is the bearing of the wicked conduct upon Jehovah and His rights. Hence the phenomenon that the conduct of the rich is condemned in equally strong terms even where it does not directly affect the lot of the poor and the weak.”
