Tatnai
gift, a Persian governor (Heb. pehah, i.e., "satrap;" modern
"pasha") "on this side the river", i.e., of the whole tract on
the west of the Euphrates. This Hebrew title _pehah_ is given to
governors of provinces generally. It is given to Nehemiah (5:14)
and to Zerubbabel (Hag. 1:1). It is sometimes translated
"captain" (1 Kings 20:24; Dan. 3:2, 3), sometimes also "deputy"
(Esther 8:9; 9:3). With others, Tatnai opposed the rebuilding of
the temple (Ezra 5:6); but at the command of Darius, he assisted
the Jews (6:1-13).
