Job 6:30

Is there iniquity in my tongue?.... Meaning in his words; either those which he uttered when he cursed the day on which he was born, or in charging his friends with unkindness and falsehood; otherwise the tongue is a world of iniquity, and the best of men are apt to offend both God and men in word:

cannot my taste discern perverse things? which is to be understood not of his natural taste, which very probably through his disease might be greatly vitiated, and incapable of relishing his food as in time of health, and of distinguishing good from bad; but of his intellectual taste, or of his sense and reason, his rational and spiritual taste; he had his senses exercised to discern good and evil; he could distinguish between right and wrong that was said or done, either by himself or others; be had the use of his rational powers and faculties, and therefore not to be treated as a mad or distracted man, but as one capable of carrying on a conversation, of opening his true case, and defending himself; see Job 12:11.
