Matthew Poole and continuators on Job 4:5

5. But now it is come upon thee, and thou faintest, it toucheth thee and thou art troubled.

i. e. The evil which thou didst fear, Ch. 3. 25. and which was come upon those whom thou didst so comfort.

Thou allowest in thy self what thou wouldst not bear in others. What in them was a Vice, in thee, it seems, is become a Virtue. Thou art wise for others, but not for thy self; a good Physician to cure others but not thy self; quick fighted to see the faults of others, but blind to thine own.

It is now come to be thine own case.
