Albert Barnes Commentary Job 29:1

"And Job again took up his parable, and said," — Job 29:1 (ASV)

Moreover, Job continued his parable - See the notes at (Job 27:1). It is probable that Job had paused to see if anyone would attempt a reply. As his friends were silent, he resumed his remarks and went into a fuller statement of his sufferings. The fact that Job more than once paused in his addresses to give his friends an opportunity to speak, and that they were silent when they seemed called upon to vindicate their former sentiments, was what particularly roused the wrath of Elihu and induced him to answer (Job 32:2–5).
