Flag. There are two Hebrew words rendered "flag" in our Bible:
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; Genesis 41:18, (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; Exodus 2:5; Isaiah 19:6.
