Jeremiah 36:23

Three or four leaves— Their books were in the form of a scroll, and consisted of several pieces of parchment rolled upon each other. It must be likewise noted, however, that by leaves several understand columns or partitions, into which the breadth of the parchment was divided. A variety of Hebrew manuscripts in the Bodleian library, as well as a curious one found at Herculaneum, are evidences for the reality of this manner of writing. Houbigant reads pages; which, says he, were the same with those now found in the parchments called "The volumes of the synagogue;" in which the parchments are not sewn one beneath the other; for if this was the case, the volume would only have one page, whose beginning would be at the top, and its end at the bottom of the parchment: but the parchments are sewn on the side of each other; which are read by unfolding the volume either to the right or left; so that there are as many pages as there are parchments.
