Made old - Or, wasted: his strength slowly wasted as he pined away in sorrow.
He hath broken my bones - This clause completes the representation of the sufferer‘s physical agonies. Here the idea is that of acute pain.
Matthew Henry
Concise Bible Commentary
The prophet relates the more gloomy and discouraging part of his experience, and how he found support and relief. In the time of his trial the Lord had become terrible to him. It was an affliction that was misery itself; for sin makes the cup of affliction a bitter cup. The struggle between unbelief and faith is often very severe. But the weakest believer is wrong, if he thinks that his strength and hope are perished from the Lord.
