When Sanballat the Horonite, and Tobiah the servant, the Ammonite, heard of it, it grieved them exceedingly that there was come a man to seek the welfare 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.
