“paper reeds” (Isaiah 19:7; Revised King James Version, “reeds”)
Hebrew: 'aroth, properly green herbage growing in marshy places.
Hebrew: kaneh (1 Kings 14:15; Job 40:21; Isaiah 19:6), whence the Greek kanna, a “cane,” a generic name for a reed of any kind
The reed of Egypt and Israel is the Arundo donax, which grows to the height of 12 feet, its stalk jointed like the bamboo, “with a magnificent panicle of blossom at the top, and so slender and yielding that it will lie perfectly flat under a gust of wind, and immediately resume its upright position.” It is used to illustrate weakness (2 Kings 18:21; Ezek. 29:6), also fickleness or instability (Matthew 11:7; compare Ephesians 4:14).
A “bruised reed” (Isaiah 42:3; Matthew 12:20) is an emblem of a believer weak in grace.
A reed was put into our Lord's hands in derision (Matthew 27:29); and “they took the reed and smote him on the head” (30).
The “reed” on which they put the sponge filled with vinegar (Matthew 27:48) was, according to John (19:29), a hyssop stalk, which must have been of some length, or perhaps a bunch of hyssop twigs fastened to a rod with the sponge.
