she-naz'-ar (shen'atstsar): A son of Jeconiah (Jehoiachin) and uncle of Zerubbabel (1 Chronicles 3:18, Codex Vaticanus and Codex Alexandrinus Sanesar; Lucian, Sanasar; Vulgate (Jerome's Latin Bible, 390-405 A.D.) Sennaser, Senneser). It is highly probable that Sheshbazzar (Ezra 1:8, 11), "the prince of Judah," and Shenazzar are identical (so Meyer, Rothstein, etc.). The name is difficult; some suggest a corruption of shushbalatstsar, and as equivalent to Sin-usur, "Sin (the moon-god) protect."
Shenazzar (1 Occurrence)
1 Chronicles 3:18 and Malchiram, and Pedaiah, and Shenazzar, Jekamiah, Hoshama, and Nedabiah. (WEB JPS ASV BBE DBY YLT NAS NIV)
