Musar su Salmi 34:12

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.”

A remedy for this is to imagine that he and the people of his city came down with a severe malady, G-d forbid, to the point that all the doctors of the city despaired of finding a cure for it, and it was heard that there had come to the city a great doctor, universally renowned and unrivaled for his treatments of this malady, which restored the hopeless patient to his former state, so that no trace of the malady was visible in him. Would he hesitate to send immediately for this doctor to come and see him in his suffering on his sickbed in the hope that he might cure him of his illness? And if one of his loved ones would ask him: "Why are you more zealous than others?" would he not answer: "Fool, where my life is at stake, I would not look at others even if there were a possibility of a possibility [that I might be saved]! How much more so with this doctor, whom we know, ourselves, from the past and who is universally renowned for his awesome cures of all desperate illnesses, would I abandon my life for the sake of these fools who have no mercy on their lives?" And if this is so with the [life of the body], how much more so with the soul! For we know that one who guards his tongue from evil will merit living eternal life in the world to come, as it is written (Psalms 34:12-13): "Go my sons … Who is the man who desires life, etc." And who is a more trusted physician than our lord, David, may peace be upon him? And, otherwise, [i.e., if we did not follow his regimen], there is no cure for this illness eternally. And in this world, too, in the end there will come upon him because of this [lashon hara] great suffering and pain. How much more so should he pay no heed in this to others!

From these verses we learn that Israel is obligated to fear God, Blessed be He, and to occupy themselves with meditation over His Torah, and to fulfill His commandments and that from their meditation over the Torah they will understand the meaning of its directives and the new interpretations that may be obtained from each verse and they will grow wise in order to know God, may He be Blessed, and His strength and His power and his greatness and His great works, awesome and wondrous, as it is written, "Say unto God : 'How tremendous is thy work!' " (Ps. 66:3). And it is written, "Come, ye children, hearken unto Me; I will teach you the fear of the Lord" (Ps. 34:12).
