a title probably of Persian origin, meaning “severity,” denoting a high civil dignity
The Persian governor of Judea is so called (Ezra 2:63; Neh. 7:65, 70). Nehemiah is called by this name in Neh. 8:9; 10:1, and the “governor” (pehah) in 5:18. Probably, therefore, tirshatha = pehah = the modern pasha.
