And the books - It is impossible to determine what books are meant here. They may have been portions of the Old Testament, or classic writings, or books written by other Christians, or by himself. It is worthy of remark that even Paul did not travel without books, and that he found them in some way necessary for the work of the ministry.
Especially the parchments - The word here used (μεμβράνας membranas, whence our word "membrane"), occurs only in this place in the New Testament, and means skin, membrane, or parchment. Dressed skins were among the earliest materials for writing, and were in common use before the art of making paper from rags was discovered. These "parchments" seem to have been something different from "books," and probably refer to some of his own writings. They may have contained notes, memorandums, journals, or unfinished letters. It is, of course, impossible now to determine what they were. Benson supposes they were letters which he had received from the churches; Macknight, that they were the originals of the letters which he had written; Dr. Bull, that they were a kind of common-place book, in which he inserted hints and extracts of the most remarkable passages in the authors which he read. All this, however, is mere conjecture.
