Bulrush. Isaiah 18:2, A. V.; "papyrus" in R. V. A species of reed found on the marshes of the Nile, and grows to the height of twelve or fifteen feet. The stalks are pliable, and capable of being interwoven very closely, as is evident from its being used in the construction of the "ark" or boat-cradle in which Moses was hid by his mother. Exodus 2:3; Exodus 2:5. It was from this vegetable that the papyrus was derived, which was used for writing. It was made of the inside bark, which was cut into strips, and the edges cemented together, and dried in the sun. The fact that the papyrus was used for food when prepared in one way, and for writing when prepared in another way, explains the passages in which the eating of books, etc., is mentioned. Jeremiah 15:16; Ezekiel 3:1; Ezekiel 3:3; Revelation 10:8-10.
