Charles Ellicott Commentary Nehemiah 4:7

"But it came to pass that, when Sanballat, and Tobiah, and the Arabians, and the Ammonites, and the Ashdodites, heard that the repairing of the walls of Jerusalem went forward, [and] that the breaches began to be stopped, then they were very wroth;" — Nehemiah 4:7 (ASV)

Were made up. —Arose to the height previously mentioned.

Began to be stopped. —The wall, they heard, was continuous. The tribes here enumerated were only small parties under the immediate influence of Sanballat: nothing beyond that would have been likely to occur among common subjects of Persia.
