Meaning
Among the conjectures as to the meaning and derivation of the name, the following may be mentioned:
(1) Shethar-boznai may be a corruption of metharboznay = Mithrobouzanes, Old Persian Mithrobauzana-i.e. "Mithra is deliverer."
(2) shathar is identical with the Old Persian Tsithra ("seed," "brilliance"); names have been found that are confounded with this word.
(3) shethar bowzenay may be a title, but sethar, must then be read for shethar.
(4) shethar boznay is equivalent to the Old Persian Sethrabuzana, "empire-delivering"; compare Encyclopedia Biblica, article "Shethar-boznai," and Brown, Driver, and Briggs, Hebrew and English Lexicon of the Old Testament.
