In Job 16:2, Job calls his friends 'miserable comforters' — the very consolation he seeks in 21:2 they fail to give.

In Job 10:1, Job declares he will give free utterance to his complaint — here he asks them to listen to that complaint.

In Job 13:5, Job wished his friends would be silent — now he asks them to listen, a shift in his approach.

In Job 13:6, Job similarly asks them to hear his argument — a parallel plea for attentive listening.

Job 33:1 has Elihu asking Job to listen, directly echoing Job's own request for a hearing in Job 21:2.

Job 33:31-33 continues Elihu's call for Job to listen and be silent—a strong parallel to Job's earlier plea for attention.

In Job 15:11, Eliphaz asks if God's consolations are insufficient — contrasting with Job's plea for consolation through listening.
