When Balak first tried to persuade Bila'am to join him and curse the Jewish people, Bila'am tried to make very clear that he would only be able to do whatever it is that hashem wants him to do.
Later, after Bila'am's multiple failed attempts, in 24:13, Bila'am, again, says, "If yo give me a house full of gold and silver, I would not beable to go against what Hashem wants me to do..."
I am no ba'al mussar, but I find this situation striking. Bila'am Ha'Rasha, who claims to know how to manipulate Hashem and find the moment He gets angry and take advantage by cursiong the jews at that very moment, he stands up and says that no sum of money, no matter how great it might be, will allow him to act against Hashem.
What about us? How often do we, for even just a small monetary gain, allow ourselves to be lax and derelict in our obligations towards Hashem?
How great it would be if we would have the wherwithal of Bila'am to be able to say with full confidence that no amount of money will make a difference in our allegiance to Hashem!
