Job 35:13 - Albert Barnes' Notes on the Bible

Surely God will not hear vanity - A vain, hollow, heartless petition. The object of Elihu here is to account for the reason why sufferers are not relieved - having his eye, doubtless, on the case of Job as one of the most remarkable of the kind. The solution which he here gives of the difficulty is, that it is not consistent for God to hear a prayer where there is no sincerity. Of the “truth” of the remark there can be no doubt, but he seems to have taken it for granted that all prayers offered by unrelieved sufferers are thus insincere and hollow. This was needfull in his view to account for the fact under consideration, and this he “assumes” as being unquestionable. Yet the very point indispensable to make out his case was, that “in fact” the prayers offered by such persons were insincere.
