Hast thou heard the secret of God? - "Hast thou hearkened in God's council?" Wert thou one of the celestial cabinet, when God said, Let Us make man in Our image, and in Our likeness?
Dost thou restrain wisdom to thyself? - Dost thou wish us to understand that God's counsels were revealed to none but thyself? And dost thou desire that we should give implicit credence to whatsoever thou art pleased to speak? These are all strong sarcastic questions, and apparently uttered with great contempt.
Hast thou heard the secret of God? - literally, “in the secret of God hast thou heard” - הסוד hasôd The word rendered “secret” (סוד sôd ) means properly a “couch” or “cushion,” on which one reclines - whether for sleep or at a table, or as a divan. Hence, it means a divan, or circle of persons sitting together for familiar conversation, Jeremiah 6:11; Jeremiah 15:17; or of judges, counsellors, or advisers for consultation, as the word “divan” is now used in Oriental countries; Psalm 89:7; Jeremiah 33:18. Then it means any consultation, counsel, familiar conversation, or intimacy; Psalm 55:14; Proverbs 15:22. Here God is represented in Oriental language as seated in a “divan,” or council of state: there is deliberation about the concerns of his government; important questions are agitated and decided; and Eliphaz asks of Job whether he had been admitted to that council, and had heard those deliberations; and whether, if he had not, he was qualified to pronounce as he had done, on the plans and purposes of the Almighty.
And dost thou restrain wisdom to thyself? - Having obtained the secret of that council, art thou now keeping it wholly to thyself - as a prime minister might be supposed to keep the purposes resolved on in the divan? “Hast thou listened in the council of yahweh, and dost thou now reserve all wisdom to thyself?”
