Numbers 23:14

And he brought him into the field of Zophim,.... Or Sede Tzophim, as Hillerus i reads it, so called from the watch tower, and watchmen in it: Jarchi says, it was a high place, where a watchman stood to observe if an army came against a city, and so a very proper place to take a view of the armies of Israel from:

to the top of Pisgah; a high hill in this place, where perhaps the watch tower was, or, however, the watchman stood: this looked towards Jeshimon or Bethjesimoth, in the plain of Moab, where Israel lay encamped, see Numbers 21:20: and built seven altars, and offered a bullock and a ram on every altar: as he had done before, Numbers 23:2.
