Numbers 23:14

שדה צפים FIELD OF ZOPHIM — There was a high spot upon which the watchman (צופה) used to stand to observe whether any hostile force was coming against the city. ראש הפסגה THE TOP OF PISGAH — Balaam was not as expert a diviner as Balak. Balak forsaw that at some time a breach in Israel would originate from there — and as a matter of fact Moses died there, — and therefore he believed that there the curse would certainly fall upon them. “And this (the effects of the curse)” — he thought — “must be the breach which I behold” (Midrash Tanchuma, Balak 13).

וַיִּקָּחֵ֙הוּ֙ שְׂדֵ֣ה צֹפִ֔ים אֶל־רֹ֖אשׁ הַפִּסְגָּ֑ה וַיִּ֙בֶן֙ שִׁבְעָ֣ה מִזְבְּחֹ֔ת וַיַּ֛עַל פָּ֥ר וָאַ֖יִל בַּמִּזְבֵּֽחַ׃

And he brought him into a field of vantage, at the top of Pisga, and built seven altars, and offered a bullock and a ram on every altar.
