Numbers 24:25

25. Balaam… returned to his place Not to Mesopotamia. Literally, he turned toward his own place. This he never reached. Having privately advised Balak to ensnare Israel into idolatry and its vices by the blandishments of the women of Moab and Amalek, (Numbers 31:16,) he lingered in the vicinity to see the result of his wicked counsel, and was slain in battle when Jehovah, avenging the Israelites, ordered them to war against Midian. Numbers 31:8. Hengstenberg suggests that Balaam, smarting under the indignity of his summary dismissal by Balak, went into the camp of Israel, rehearsed to Moses his prophecies in hope of a reward, was coolly treated, and, goaded on by disappointed ambition and covetousness, went to the Midianites, and counselled the seduction of Israel to whoredom and idolatry.
