Or HaChaim on Numbers 24:11/אור החיים על במדבר כ״ד:י״א

1 ועתה ברח לך, "And now, you better flee for yourself, etc." Balak decreed four penalties against Bileam. 1) He was not allowed to remain in Moav but was forced to return home (in disgrace). 2) He should make haste, i.e. ברח, "flee." 3) He should go by himself without attendants, i.e. לך "by yourself." 4) He was not to go from this city of Moav to another city or even to Midian but straight to his home, מקומך, "your place." Balak explained to Bileam that if he was forced to belittle him in this fashion though he had previously boasted about his ability to confer a lot of honour on him (22,17), this was only because G'd did not want Bileam to receive this honour, i.e. הנה מנעך השם מכבוד. Balak appears to have interpreted G'd's refusal for Bileam to curse the Jewish people as only a stratagem to prevent Bileam from being honoured.

2Bileam immediately denied this argument when he reminded Balak that he had already told the delegates that he would only be able to say what G'd would tell him, and that Balak had insisted that he should come all the same. Bileam reminded Balak that he had repeated the word כבד אכבדך, i.e. he had insisted that Bileam should come because he wanted to honour him regardless of what he would say. He also repeated the words: "your delegates whom you sent," although the words "whom you have sent" were quite redundant, because he also referred to the first set of emissaries. The word מלאכיך refers to the second set of delegates, the words אשר שלחת refer to the first set of emissaries. He added the word לאמור to remind Balak that he had not only told the emissaries what was on his mind, but had asked them at the time to make sure that they would convey this to Balak.
