Nehemiah 2:9-10 NLT

9 When I came to the governors of the province west of the Euphrates River, I delivered the king's letters to them. The king, I should add, had sent along army officers and horsemen to protect me.
10 But when Sanballat the Horonite and Tobiah the Ammonite official heard of my arrival, they were very angry that someone had come who was interested in helping Israel.
