Musar su Levitico 19:32

And the fulfillment of positive commandments is called, fear of Heaven; [just] like carefulness is [understood as] the negative commandments. For it is stated (Leviticus 19:32), “You shall rise before the aged and show deference to the old; you shall fear your God; I am the Lord.” And it is [also] stated (Psalms 34:12), “I will teach you fear of the Lord”; and after it is stated (Psalms 34:15), “Shun evil and do good, seek peace and pursue it.” We learn from this, that one who is not occupied with doing good and seeking peace annuls fear of Heaven. And he is from the evildoers, since he has no fear of God, as it is stated (Ecclesiastes 8:13), “And it will not be well with the evildoer, and he will not live long, because he does not fear God.”

The Torah has stipulated this in 19,32: והדרת פני זקן. The Torah scholar is entitled to our respect because by his teaching us Torah he enables us to inherit a life of unlimited duration in the Hereafter and to avoid being consigned to purgatory.

And how foolish are those people in whose eyes it is a light matter to argue with the Rabbi and the beth-din of the city and to shame them, not fearing the great punishment awaiting them for this in the world to come, as we have explained. And also in this world they will not escape sore judgment because of this. Come and see what we find in Midrash Rabbah, Parshath Pinchas on the verse [Vayikra 19:32]: "And you shall honor the face of the elder," (which refers to a Torah scholar), as we find in Kiddushin 32b: "What is the intent of 'And you shall honor'? That you not stand in his place, nor sit in his place, nor contradict his words, etc. For one who does not conduct himself thus with his Rabbi is called 'wicked' before the L-rd, and his learning is forgotten, and his years are shortened, and in the end he becomes impoverished. As it is written (Koheleth 8:13): 'And it shall not be well with the wicked one, and he shall not prolong days, like a shadow, because he does not fear G-d.'" Now this Midrash applies even if he does not fear him as he should. How much more so if he draws upon him machloketh from the men of his city, in which instance he will certainly be doubly punished.
