kos-a-me'-us (A, Simon Chosamaios; B, Chosamaos): Occurs in 1 Esdras 9:32 as the name of one of the sons of Annas. But in the parallel passage (Ezra 10:31) the name is simply Shimeon followed by "Benjamin, Malluch, Shemariah," which are omitted in 1 Esdras. The Septuagint of Ezra 10:31 has Semeon, followed by the three omitted names. The difference may have arisen from a mistake of a copyist, or from the use of an imperfect MS.
