Matthew Poole and continuators on Job 22:11

11. Or darkness that thou canst not see, and abundance of Waters cover thee.

Either 1. A darkness and confusion of mind, so great that thou canst not discern the true cause and use of all thy sufferings Or 2. Grievous Calamities, which are oft called darkness, which are such that thou canst see no way nor possibility of escaping. Either thou art troubled with fear of further evils, as it is said, v. 10. or with the gross darkness of thy present state of misery.

i. e. Plenty and variety of sore afflictions, which are frequently compared to Waters, as Psal. 18. 16. & 66. 12. Isa. 43. 2.
