Midrash sa Mga Kawikaan 1:2: Midrash Mishlei, Mekhilta DeRabbi Yishmael, Sifrei Devarim & Midrash Tehillim

[2] (Proverbs 1:2): 'To know wisdom and discipline' - If [it's about] wisdom, why [mention] discipline? And if [it's about] discipline, why [mention] wisdom? Rather, if a person has wisdom, he can learn discipline, and if a person doesn't have wisdom, he cannot learn discipline. Alternatively, 'To know wisdom and discipline' - if a person has wisdom, the words of the Torah are entrusted to him, and if he doesn't have wisdom, the words of the Torah are not entrusted to him. 'To understand words of understanding' - a person must have understanding, to understand one thing from another."

R. Shimon b. Yochai says: Beloved are afflictions, for three goodly gifts were given to Israel and are desired by the nations of the world, and they were given to them only through afflictions — Torah, Eretz Yisrael, and the world to come. Torah, (Mishlei 1:2) "to know wisdom and chastisement, to comprehend words of understanding," and (Psalms 94:12) "Happy is the man whom you chastise, O L–rd, and whom you teach from Your Torah." Eretz Yisrael, (Devarim 8:5) "… the L–rd your G–d chastises you … (7) for the L–rd your G–d brings you to a good land." The world to come, (Mishlei 6:23) "For a mitzvah is a lamp, and Torah, light, and the way of life, the chastisements of mussar." Which is the way which leads a man to life in the world to come? Afflictions.

Torah — (Proverbs 1:2) "To know wisdom and mussar (chastisement)," and (Psalms 94:12) "Happy is the man whom You chastise, O L-rd, and whom You teach from Your Torah."
