Albert Barnes Commentary Job 12:16

"With him is strength and wisdom; The deceived and the deceiver are his." — Job 12:16 (ASV)

The deceived and the deceiver are his - This is designed to teach that all classes of people are under His control. All are dependent on Him, and all are subject to Him. He has power to keep them, and He can destroy them when He pleases. Dr. Good supposes that Job refers here to himself and his friends who had beguiled him into expressions of impatience and complaint. But it is more probably a general declaration that all classes of people were under the control of God.
