Numbers 22:41

Bamos Ba’al. As Targum [Onklos] renders, “To the heights of his deity.” [Ba’al is] the name of an idol.

And at the time of the morning Balak took Bileam, and brought him up to the high place of the idol Peor; saw from thence the camp of Dan, which went at the rear of the people; and they were discovered under the Cloud of Glory.

[AND IT CAME TO PASS IN THE MORNING AND BALAK TOOK BALAAM] AND BROUGHT HIM UP INTO BAMOTH-BAAL, AND HE SAW FROM THENCE THE UTMOST PART OF THE PEOPLE. Balak took him up to a [high] place from which he could see them [the people of Israel], in order that he could concentrate his curse upon them, and his mind would not separate itself from them, for it is one of the attributes of the soul’s powers that it attaches itself at the time of seeing a certain object as is known from that which the Sages tell [of Rabbi Yochanan, that he said to his disciples]: “‘Lift up my eye-lids for me, because I want to see [this scholar].’ They [accordingly] lifted up his eye-lids. He set his eyes upon him, and [as a result] that person died.”
Now Scripture relates that Balaam did not see the whole camp [of Israel] because they were encamped in four standards [positioned in all] four directions of the heaven. On the second occasion Balak said to him, thou shalt see but the utmost part of them, and shalt not see them all, meaning: “this time also you will not [be able to] see them all, if that is what prevents you from cursing them, but [nonetheless] curse me them from thence if you can, for I do not have any place from where I can show you all of them.” Balak thought that perhaps there was a standard in one of the sections [of the camp of the Israelites] consisting of righteous and good people whom it pleased not the Eternal to crush, [and therefore Balak took Balaam to other places from which Balaam could see other parts of the camp, in order to curse them effectively].
It is also possible to explain that on the first occasion [referred to in this verse] Balaam did see the whole camp, for Bamoth-baal is a high place, and from there both of them [Balak and Balaam] saw part of the people, and built the altars there; then Balaam ascended to the peak of the hill on that mountain, and saw the whole people, this being the meaning of [the expression] and he [Balaam] went ‘shephi,’, Verse 3. which means he went to “the height” thereof, as Rabbi Abraham ibn Ezra has explained.

וירא משם קצה העם, in order to harm them by focusing his evil eye on them. Compare kings II 2,24 ויפן אחריו ויראם ויקללם, “He turned around and cursed them in the name of the Lord.” (the prophet Elisha cursed the lads who had insulted him) Deuteronomy 34,1 is an example of the very reverse, i.e. bestowing a blessing. Moses looked at the people with a benevolent eye, i.e. he blessed them.

וירא משם קצה העם, “from that point he was able to see part of the people.” Our author understands these words as meaning that he saw the entire nation from one end (קצה) of the camp to the other.
