Chasidut zu Bamidbar 22:37

Having explained all this, the opening line of our portion, i.e. ‎Balak’s fear of the Israelites, which had baffled many in light of ‎G’d having forbidden the Israelites to harass the Moabites, much ‎less attack them, becomes more understandable.‎
It is true that Nachmanides had addressed this problem and ‎concluded that Balak’s fear was that the Moabites, on account of ‎their love or their being related to the founder of the Jewish ‎people, would voluntarily allow themselves to be conquered, as a ‎result of which the prohibition to attack and conquer their ‎territory would have become null and void, and the Israelites ‎would conquer that land, just as they had done with the land ‎owned by Sichon and Og, annex it. Nonetheless, this is not a very ‎plausible explanation as there were no nations nearby other than ‎the Canaanites, all of whom Israel had been commanded to wipe ‎out completely, so that the Moabites would not gain by becoming ‎their captives. [Since the author had introduced an even ‎less likely scenario than the example I mentioned, examples that ‎reflect Balak’s supposed fear of the Israelites through devious ‎means trying to elevate the Moabites spiritually, level by level, I ‎have omitted it. Ed.]‎
When commenting on Deut. 34,10, ‎ולא קם נביא עוד בישראל ‏כמשה‎, “and there never arose another prophet of the stature of ‎Moses in Israel,” our sages in Sifrey Vezot Habrachah, draw ‎our attention to the significance of the word ‎בישראל‎, “in Israel,” ‎in that verse, and suggest that it means that within other nations ‎there did arise at least one prophet of a stature equal or superior ‎to that of Moses. The statement is mind-boggling, and they ‎therefore add that any comparison of Moses and Bileam is limited ‎to certain aspects of their respective prophetic knowledge and ‎power.‎
