  Bulrush
     (1.) In Isa. 58:5 the rendering of a word which denotes
     "belonging to a marsh," from the nature of the soil in which it
     grows (Isa. 18:2). It was sometimes platted into ropes (Job.
     41:2; A.V., "hook," R.V., "rope," lit. "cord of rushes").
       (2.) In Ex. 2:3, Isa. 18:2 (R.V., "papyrus") this word is the
     translation of the Hebrew _gome_, which designates the plant as
     absorbing moisture. In Isa. 35:7 and Job 8:11 it is rendered
     "rush." This was the Egyptian papyrus (papyrus Nilotica). It was
     anciently very abundant in Egypt. The Egyptians made garments
     and shoes and various utensils of it. It was used for the
     construction of the ark of Moses (Ex. 2:3, 5). The root portions
     of the stem were used for food. The inside bark was cut into
     strips, which were sewed together and dried in the sun, forming
     the papyrus used for writing. It is no longer found in Egypt,
     but grows luxuriantly in Palestine, in the marshes of the Huleh,
     and in the swamps at the north end of the Lake of Gennesaret.
