Job 6:30

In Job 6:28 Job asseverated that he spoke truth in affirming his innocence. In Job 6:29 he affirmed that he had right on his side in his plea against God, in other words that he was wrongly afflicted. This verse, therefore, can hardly be a new assertion that he speaks the truth when he affirms his innocence; it must refer to a point further back, and be, in the form of a question, an affirmation of his ability to say whether he is innocent or not, and to judge rightly regarding the nature of his afflictions. The question, Is there iniquity in my tongue? means Is my tongue perverted that it cannot distinguish? In the second clause "taste" or "palate" is not referred to as an organ of speech but of perception (ch. Job 12:11).

The expression "perverse things" may mean wickednesses. This may be used generally and the question in the second clause have the same meaning as that in the first, viz. whether Job had lost moral sense and could not distinguish wrong from right? And the whole would be an affirmation of the soundness of his moral judgments, meant to support the asseveration of his innocence and the righteousness of his cause (Job 6:28). The phrase "perverse things" is that rendered "calamity" Job 6:2, and this might be the meaning here: "cannot my taste discern calamities?" i. e. the true nature of my afflictions, and perceive that they are undeserved and unjust?

Either of the above meanings forms a fitting and pathetic transition to the renewed cry of despair in ch. 7. For that which makes Job's condition so crushing to him is that though innocent he feels himself in the hands of a ruthless and arbitrary fate, which, regardless of his innocence, is bent on destroying him. For this fate he has no other name but God; cf. ch. Job 9:22 seq., Job 23:13 seq.
