Now it is come, i.e. the evil which thou didst fear, Job 3:25, and which was come upon those whom thou didst so comfort. Thou faintest; thou allowest in thyself 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 thyself; a good physician to cure others, but not thyself; quick-sighted to see the faults of others, but blind to thine own. It toucheth thee; it is now come to be thine own case.
