Musar zu Tehillim 45:2

As we find with the sons of Korach, that because they were not drawn after their father, even though this caused him great shame, they escaped his fate. As we find in Yalkut Parshath Korach: "This is as Scripture writes (Psalms 1:1): 'Happy is the man' — the sons of Korach; 'who did not walk in the counsel of the wicked' — who did not walk in the counsel of their father, as it is written (Numbers 16:26): 'Depart now from the tents of these wicked men'; 'and in the way of sinners they did not stand,' as it is written (Numbers 17:3): 'the censers of these sinners.'" And, in Yalkut: "What merit was there 'in the hands' of the sons of Korach that they were rescued [from his punishment]? When they were sitting with Korach, their father, they saw Moses and lowered their faces to the ground, saying: "If we stand up for Moses our teacher, we will be spurning our father, whom we have been commanded to honor. And if we do not stand, it is written (Vayikra 19:32): 'Before the hoary head shall you rise' — Better that we stand before Moses our teacher, even though we are thereby spurning our father.'" At that time, they moved their hearts to repentance. About them David said (Psalms 45:2): 'My heart has stirred with a good thing.'" From this we learn that if one is not drawn after his father's counsel in his machloketh, he will not be ensnared in his net.
