잠언 6:23 탈무드 참조: Berakhot, Taanit & Megillah

And the world to come ? For it is written, "For the commandment is a lamp, and the teaching is light, and reproofs of instruction' are the way of life" (Prov. vi. 23).

Rav Yosef quoted from the following, "'And now they shall see no clear light in the heavens, but a spirit shall pass and purify them,' and there is no such term as light except for Torah, as it says, 'For a candle is the commandment, and the Torah is a light.' "Clear in the Heavens:" it was taught at the school of Rabbi Yishmael, Even in the time that the sky is made clear to bring dew and rain, a spirit passesand purifies them.

“The Jews had light and gladness and joy and honor” (Esther 8:16). Rav Judah said: “Light” means the Torah, and so it says, “For the commandment is a lamp and the Torah is a light” (Proverbs 6:23). “Gladness” means a festival day; and so it says, “And you shall be glad on your festival” (Deuteronomy 16:14). “Joy” means circumcision; and so it says, “I rejoice at Your word” (Psalms 119:162).
