The headword, evidently quoted from somewhere (probably the Septuagint: Ecclesiasticus 33.16), is the masculine nominative singular middle active participle of the verb καλαμάω . See also kappa 194, kappa 197.
[2] This third person plural, present indicative middle, of the same verb (again kappa 200) is doubtless quoted from, again, the Septuagint: see Isaiah 3.12, where its figurative use could bear this gloss.
