Int. Standard Bible Encyclopedia
she-ma'-a, shem'-a-a (ha-shema`-ah; Codex Vaticanus Ama, Codex Alexandrinus Samaa, Lucian, Asma): A Benjamite, who was the father, according to the Massoretic Text, of Ahiezer and Joash; but according to the Septuagint huios = (ben) instead of (bene) of Joash alone (1 Chronicles 12:3). The original text may have read ben yeho-shama` (compare hoshama`, of 1 Chronicles 3:18); then a dittography of the following (h) caused the error (Curtis, ICC).
