Rabbi Ammi expounded on the words, "For it is a pleasant thing if you keep them of the wise within you; let them be established altogether upon your lips," in . He explained that the words of the Torah are "pleasant" when one keeps them within oneself, and one does that when the words are "established altogether upon your lips." Rabbi Isaac said that this may be derived from the words of "But the word is very near to you, in your mouth, and in your heart, that you may do it," for "it is very near to you" when it is "in your mouth and in your heart" to do it. Thus, reading the Torah aloud helps one to keep its precepts in one's heart, and thus to carry them out.
