(Heb., or rather Egyptian, ahu, Job 8:11), rendered "meadow" in
Gen. 41:2, 18; probably the Cyperus esculentus, a species of
rush eaten by cattle, the Nile reed. It also grows in Israel.

In Ex. 2:3, 5, Isa. 19:6, it is the rendering of the Hebrew
"suph", a word which occurs frequently in connection with "yam";
as "yam suph", to denote the "Red Sea" (q.v.) or the sea of
weeds (as this word is rendered, Jonah 2:5). It denotes some
kind of sedge or reed which grows in marshy places. (See PAPER
