Is there iniquity in my tongue? - Am I not an honest man? and if in my haste my tongue had uttered falsity, would not my conscience discern it? and do you think that such a man as your friend is would defend what he knew to be wrong?
I Have done what I could to make this chapter plain, to preserve the connection, and show the dependence of the several parts on each other; without which many of the sayings would have been very obscure. The whole chapter is an inimitable apology for what he had uttered, and a defense of his conduct. This might have ended the controversy, had not his friends been determined to bring him in guilty. They had prejudged his cause, and assumed a certain position, from which they were determined not to be driven.
Is there iniquity in my tongue? - This is a solemn appeal to their consciences, and their own deep conviction that he was sincere. Iniquity in the tongue means falsehood, deceit, hypocrisy - that which would be expressed by the tongue.
Cannot my taste discern perverse things? - Margin, palate. The word used here חך chêk means properly the palate, together with the corresponding lower part of the mouth, the inside mouth. Gesenius. Hence, it means the organ of taste, residing in the mouth. The meaning is, that Job was qualified to discern what was true or false, sincere or hypocritical, just or unjust, in the same manner as the palate is fitted to discern the qualities of objects, whether bitter or sweet, pleasant or unpleasant, wholesome or unwholesome. His object is to invite attention to what he had to state on the subject. To this proposed vindication he proceeds in the following chapter, showing the greatness of his calamity, and his right, as he supposes, to complain. Their attention was gained. They did not refuse to listen to him, and he proceeds to a fuller statement of his calamity, and of the reasons why he had allowed himself to use the language of complaint. They listened without interruption until he was done, and then replied in tones of deeper severity still.
