Job 33:32

If thou hast anything to say, answer me - In the previous verse, Elihu had asked that Job would hear all that he had to say. Yet here, in view of what he had said, he asks of him that if there were any thing from which he dissented, he would now express his dissent. We may suppose that he paused at this part of his speech, and as what he had said related particularly to Job, he felt that it was proper that he should have an opportunity to reply.

For I desire to justify thee - I would do you justice. I would not pervert what you have said, or attribute to you any wrong opinions or any improper motives Perhaps there may be included also a wish to vindicate him, if he possibly could. He did not desire to dispute for the sake of disputing, or to blame him if he could avoid it, but his aim was the truth; and if he could, he wished to vindicate the character of Job from the aspersions which had been cast upon it.
