Adam Clarke, on Neh 2:10

“And Sanaballat the Horonite, and Tobias the servant, the Ammonite, heard it, and it grieved them exceedingly, that a man was come, who sought the prosperity of the children of Israel.”

“Sanballat the Horonite - Probably a native of Horonaim, a Moabite by birth, and at this time governor of the Samaritans under the king of Persia. Tobiah the servant - He was an Ammonite; and here, under the Persian king, joint governor with Sanballat. Some suppose that the Sanballat here mentioned was the same who persuaded Alexander to build a temple on Mount Gerizim in favor of the Samaritans. Pelagius thinks there were two governors of this name.”
