Flag

International Standard Bible Encyclopedia

Two Hebrew words:

(1) סוּף , ṣūph (Exodus 2:3 , Exodus 2:1 , "flags"; Isaiah 19:6 , "flags"; Jonah 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 ṣūph .

(2) אחוּ , 'āḥū (Genesis 41:2 , Genesis 41:18 , 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.
