Some question the status of Elihu's interruption and didactic sermon because of his sudden appearance and disappearance from the text. Even scholars who regard the book of Job as a literary composition by a single author tend to see in Elihu's speeches an early addition or commentary to the original book. He is not mentioned in Job 2:11, in which Job's friends are introduced, nor is he mentioned at all in the epilogue, 42:7–10, in which God expresses anger at Job's friends. He does not say anything that is not said more succinctly by the three original friends or by God, and his speech contains more Aramaisms than the rest of the book.
