Now Elihu had waited till Job had spoken
Made an end of speaking, until he had thus expressed himself, "the words of Job are ended", ( Job 31:40 ) : and waited likewise until his three friends had said all they had to say, and which is here supposed and implied, as appears by what follows:
because they [were] elder than he;
it may be added, from the original text, "in", or "as two days" F12; they had lived longer in the world than he, and therefore did not take upon him to speak till they had done; he, as became a young man, was swift to hear, and slow to speak; that they were old men, appears from what Eliphaz says, ( Job 15:10 ) .
