Charles Ellicott Commentary Job 34:33

"Shall his recompense be as thou wilt, that thou refusest it? For thou must choose, and not I: Therefore speak what thou knowest." — Job 34:33 (ASV)

Should it be according to thy mind? is obscure from its abruptness. We understand it as follows: “Should he recompense it (i.e., a man’s conduct) according to your mind, with your concurrence, whether you refuse or whether you choose?”

And not I — i.e., “Then why not according as I refuse or choose? If you are to influence and direct His dealing and government, why may not I? why may not any one? And if so, He is no longer supreme or absolute. What do you know, then? Speak, if you have anything to say to this reasoning.”
