Jamieson, Fausset & Brown, 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--Horonaim being a town in Moab, this person, it is probable, was a Moabite. Tobiah the servant, the Ammonite--The term used indicates him to have been a freed slave, elevated to some official dignity. These were district magistrates under the government of the satrap of Syria; and they seem to have been leaders of the Samaritan faction.”
