Adam Clarke Bible Commentary
Why do ye persecute me as God - Are not the afflictions which God sends enough? Do ye not see that I have as much as I can bear? When the papists were burning Dr. Taylor at Oxford, while wrapped in the flames, one of the true sons of the Church took a stick out of the faggots, and threw it at his head, and split open his face. To whom he calmly said, Man, why this wrong? Do not I suffer enough?
And are not satisfied with my flesh? - Will ye persecute my soul, while God is persecuting my body? Is it not enough that my body is destroyed? Why then labor to torment my mind?
Jamieson-Fausset-Brown Bible Commentary
as God--has persecuted me. Prefiguring Jesus Christ (Psa 69:26). That God afflicts is no reason that man is to add to a sufferer's affliction (Zac 1:15).
satisfied with my flesh--It is not enough that God afflicts my flesh literally (Job 19:20), but you must "eat my flesh" metaphorically (Psa 27:2); that is, utter the worst calumnies, as the phrase often means in Arabic.
John Gill Bible Commentary
O that my words were now written!.... Not his things (q), as some render it, his affairs, the transactions of his life; that so it might appear with what uprightness and integrity he had lived, and was not the bad man he was thought to be; nor the words he had delivered already, the apologies and defences he had made for himself, the arguments he had used in his own vindication, and the doctrines respecting God and his providence which he had laid down and asserted; and was so far from being ashamed of them, or retracting them, that he wishes they had been taken down in writing, that posterity might read and judge of the controversy between him and his friends; but rather the words he was about to deliver in Job 19:25, expressing his faith in Christ, in the resurrection of the dead, and in a future state of happiness and glory; these he wishes were "written", that they might remain as a standing testimony of his faith and hope; for what is written abides, when that which is only spoken is soon forgot, and not easily recalled:
O that they were printed in a book! not written on loose sheets, which might be lost, but in a book bound up, or rolled up in a volume, as was the custom of ancient times; though this cannot be understood of printing properly taken, which has not been in use but little more than five hundred years, but of engrossing, as of statutes and decrees in public records; and the word for "statutes comes" from this that is here used.
