Musar sobre Jó 3:19

And through it [Torah study] one merits the world to come, as Chazal have said (Peah 1:1): “These are the things … and Torah study over and against all.” And Chazal have said (Bava Metzia 85b): “That which is written (Iyyov 3:19): ‘The small and the great are there [in the next world], and the servant free of his master.’ Do we not know that the small and the great are there? — [The intent is] rather, that all who make themselves small for Torah in this world are made great in the world to come, and all who make themselves servants for Torah in this world are made free men in the world to come.” And in Avoth 6:3: “There is no honor but Torah, as it is written (Mishlei 3:35): ‘The wise will inherit honor.’ Do not desire more honor than your learning and do not lust for the table of kings. For your table [in the world to come] is greater than their table in this world, and your crown is greater than their crown, etc.” And in Sanhedrin 100a: “All who blacken their faces in Torah study in this world, the Holy One Blessed be He brightens them in the world to come, as it is written (Song of Songs 5:15): ‘His countenance is as Levanon, choice as the cedars.’” And, similarly, in Midrash Rabbah: “R. Yehudah interpreted the verse as relating to Torah scholars. One verse states (Ibid. 11) ‘black as a raven,’ and another (Nachum 2:5): ‘Their appearance is like flames, they flash like lightning.’ These are the Torah scholars, who look ungainly and black in this world but whose appearance is flamelike in the next world.” R. Tanchum ben Chanilai said: ‘All who starve themselves for words of Torah in this world, the Holy One Blessed be He sates them in the world to come, as it is written (Psalms 36:9): ‘They will be sated with the fatness of Your house.’”

A man has two masters, and when he dies he is freed from both of them. As it is said, "The small and great are there alike; and the servant is free from his master" (Job 3:19). The two masters are the spirit and the life, for they think only of pleasures, of multiplying wealth, eating, drinking, and being happy, of doing according to all the thoughts of the heart and the sight of one's eyes, and of speaking vanities and of pleasing the body. But the soul turns those thoughts upside down and says, "What good is it and what profit will there be to a man in all of his work at which he labors when in one moment he ceases to be and the body withers away, and then where is his wisdom and his beauty? If so, then there is no good except to serve the Holy One, Blessed be He, and to cleave unto Him.
