Midrasch zu Mischlej 15:23

Rabbi Shimon the son of Yochai began: "A man has joy in the answer of his mouth, and a word in season, how good it is (Proverbs 15:23)". "A man has joy", this is the Holy One, blessed be He, as it is said: "Hashem is a man of war, Hashem is his name (Exodus 15:3)". "In the answer of his mouth" [that corresponds to] "And Hashem said, let there be light." "And a word in season, how good it is" [that corresponds to] "and Hashem saw the light that it was good."

(Fol. 101) Our Rabbis were taught: If one reads a verse of Solomon's Songs, and treats it like [a secular] song, or if one reads any other verse in the drinking-places [not in its proper time], causes evil to the world, because the Torah, dresses itself in a sack, and appears before the Holy One, praised be He! saying: "Sovereign of the Universe, Thy children have made of me a fiddle on which frivolous persons play." And he sayeth to her: "My daughter with what else, then, shall they occupy themselves while they are eating and drinking?" And she says before Him: "Sovereign of the Universe, if they are masters in the Scriptures, then let them occupy themselves with the Pentateuch, Prohpets and Hagiographa; if they understand Mishnah, let them then study Mishnah, Halacha and Haggadah, and if they are Talmudists, let them study Halachoth in time of Passover on Pesach. Of Pentecost at that time. And the Halachas of Feast of Tabernacle at that time." R. Simeon b. Elazar in the name of R. Simon b. Chanania testified: "If one reads a verse in its proper time, he benefits the world, as it is said (Pr. 15, 23) And a word in due season, how good is it!"
