Or HaChaim on Numbers 24:14/אור החיים על במדבר כ״ד:י״ד

1 ועתה הנני הולך…איעצך, "And now, I am ready to go..and I will advise you, etc." On the one hand Bileam says that he will comply with the king's orders at that time. He speaks in the singular corresponding to Balak's orders that he was to leave לך, i.e. unaccompanied even by his lads. He adds the word לעמי, "to my people," to indicate compliance with Balak's orders that he was to return directly אל מקומך, "to your home." However, concerning Balak's instruction that he was to leave in a manner which reflected flight Bileam demurred. He was not scared of Balak, being a powerful enough sorcerer. It is interesting to read in the Midrash Hagadol on 31,8 how much effort even the Israelites had to make in order to succeed in killing him. If the Israelites encountered such resistance, we can imagine how much more difficult it must have been for pagans to overcome Bileam.

2אשר יעשה העם הזה לעמך באחרית הימים, "what this people will do to your people at the end of days." On the one hand Bileam wanted to reveal to Balak what Israel would to do Moav, that they would uproot the people completely. On the other hand he realised that Balak the sorcerer with the aid of צפור might already be aware of this. He therefore meant to calm Balak by telling him that what was in store for Moav would be a long time hence, nothing to worry about at this time. The reason he had to tell Balak this was that otherwise Balak might be afraid to implement his advice to seduce the Israelite males with the Moabite women. The Moabite women would be afraid even to approach the Israelites fearing they would be stabbed to death. [after all Israel had only been forbidden to invade Moav. Ed.] Bileam therefore had to reassure Balak that it would not be dangerous for his women to try and "chat up" and fraternise with the Israelites. Bileam emphasised the word לעמך, "to your people," i.e. the people over whom you are king, the Moabites. Other nations had reason to fear the Israelites already. Balak personally was not included in the words לעמך, as he was really a Midianite. Balak was killed as one of the "kings" of Midian mentioned in Numbers 31,8 (compare Bamidbar Rabbah 20,20).
