John Gill, 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.”

“When Sanballat the Horonite,.... Who either presided at Horonaim, or sprung from thence, a city of Moab, Isa 15:5 and Tobiah the servant, the Ammonite; who was formerly a slave, but now raised, from a low mean estate, to be governor in the land of Ammon, though still a vassal of the king of Persia: heard of it, it grieved them exceedingly that there came a man to seek the welfare of the children of Israel; to which the Moabites and Ammonites were always averse, and ever bore an hatred to Israel, and envied everything that tended to their happiness.”
