Job 20:3

I have heard the check of my reproach, and the spirit of my understanding causeth me to answer.

Cross-reference

Job 12:2 is the sarcastic rebuke from Job that Zophar refers to as dishonoring him — a direct contextual link.

Job 16:3 similarly questions 'windy words' — Zophar's rebuke echoes Job's own complaint about his friends' speeches.
