Flag

Flag - (Easton's Bible Dictionary)

(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 Palestine.

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 [213]PAPER, [214]REED.)

Two Hebrew words:

(1) cuph (Ex 2:3,1, "flags"; Isa 19:6, "flags"; Jon 2:5, "weeds"). This is apparently a general name which includes both the fresh-water weeds growing along a river bank and "seaweeds." The Red Sea was known as Yam cuph.

(2) 'achu (Ge 41:2,18, the King James Version "meadow," the Revised Version (British and American) "reed-grass"; Job 8:11, "Can the rush grow up without mire? Can the flag (margin "reed-grass") grow without water?"). Some such general term as "sedges" or "fens" would better meet the requirements.

1. A word of Egyptian origin, and denoting "any green and course herbage, such as rushes and reeds, which grows in marshy places." (Genesis 41:2,18) (here translated meadow). It is perhaps the Cyperus esculentus .
2. A word which appears to be used in a very wide sense to denote "weeds of any kind." (Exodus 2:3,5; Isaiah 19:6)
