Job 10:14

If I sin -The object of this verse and the following is, evidently, to say that he was wholly perplexed. He did not know how to act. He could not understand the reason of the divine dealings, and he was wholly unable to explain them, and hence, he did not know how to act in a proper manner. It is expressive of a state of mind where the individual wishes to think and feel right, but where he finds so much to perplex him, that he does not know what to do. Job was sure that his friends were not right in the position which they maintained - that he was a sinner of enormous character, and that his sufferings were proof of this, and yet he did not know how to answer their arguments.
