Isaiah 19:7

“The paper reeds by the brooks, by the mouth of the brooks, &c.] Not at the fountain or origin of the Nile and its streams, but by the sides thereof; on the banks of which grew a reed or rush, called by the Greeks “papyrus” and “biblus”; from whence come the words “paper” and “bible”, or book, of which paper was anciently made; even as early as the times of Isaiah, and so, many hundreds of years before the times of Alexander the great, to which some fix the era of making it. “According to Plinyf370, its root is of the thickness of a man’s arm, and ten cubits long; from this arise a great number of triangular stalks, six or seven cubits high, each thick enough to be easily spanned. Its leaves…”

“paper-reeds--rather, pastures, literally, "places naked" of wood, and famed for rich herbage, on the banks of the Nile [GESENIUS]. Compare Gen 13:10; Deu 11:10. HORSLEY translates, "nakedness upon the river," descriptive of the appearance of a river when its bottom is bare and its banks stripped of verdure by long drought: so Vulgate. the brooks--the river. mouth--rather, "the source" [Vulgate].

“The paper reeds - (ערות ‛ârôt). This is not the word which occurs in Isaiah 18:2, and which, it is supposed, means there the papyrus (see the note on that place). Interpreters have been divided in regard to the meaning of the word here. Gesenius derives it from ערה ‛ârâh, “to be naked, open, bare;” and supposes that it means an open place, a place naked of wood, and that it here denotes the pastures on the banks of the Nile. So Rosenmuller interprets it of the green pastures on the banks of the Nile; and the Hebrew commentators generally so understand it. The Vulgate renders it, ‘And the bed (alveus) of the river shall be dried up from the fountain.’ So the Chaldee, ‘And their streams…”

“Paper - reeds - These by a needle, or other fit instrument, were divided into thin and broad leaves, which being dried and fitted, were used at that time for writing; and consequently was a very good commodity. By brooks - And much more what was sown in more dry and unfruitful places. Isaiah 19:8”

“every: Isa 32:20; Jer 14:4; Eze 19:13; Joe 1:17, Joe 1:18 be no more: Heb. shall not be Isaiah 19:8”
