Job 2:11 introduces Eliphaz as one of Job's friends, identifying the speaker of Job 15:1.

Job 4:1 is Eliphaz's first speech, using the same introductory formula as Job 15:1—same speaker, same narrative pattern.

Job 22:1 is Eliphaz's third speech, again identical phrasing to Job 15:1.

Job 42:7 records God rebuking Eliphaz, linking back to the speaker of Job 15:1 as one who spoke wrongly.

Job 42:9 shows Eliphaz obeying God's command, concluding his role that began with speeches like Job 15:1.
