DEUT252 The goal of learning in Judaism is not merely to understand the ideas and concepts of the Torah. The purpose of learning is both to teach others and to use the learning to affect Jewish behavior. The Mishnah (Avot 4:5) says that if a person learns only for the sake of teaching, he will be granted by Heaven only the means to both learn and teach. He who learns in order to practice will be granted the opportunity to learn, teach, and, in addition, to practice and perform. The Torah speaks only about teaching (Torah and/or Judaism) to one's children [this verse and Deuteronomy 11:9) not to learn oneself (that reference comes much later in Joshua 1:8). Maimonides (Hilchot Talmud Torah 1:1 and 1:3) begins his chapters about learning Torah (after stating who is exempt) with the obligation to teach, not to learn. Two paragraphs later, he discusses the obligation and conditions for hiring a teacher. Based on the verse in Proverbs (7:26), the Talmud (Avodah Zarah 19b) deprecates someone who can teach but chooses not to. The Mishnah (Avot 1:13) also says someone who refuses to teach deserves death. On the other hand, Rabbi Joshua Ben Gamla is referred to as "remembered for good" (just as Elijah is) because he set up a Jewish school system, guaranteeing education to all children. It also says (Bava Batra 8b) that teachers are the "stars" of the Jewish people and that they do righteous behaviors for the community. Similarly, anyone who learns Torah without intention to put the learning into practice is looked down upon in Judaism. The midrash (Vayikra Rabbah 35:7) says that if a person only learns and does not do, it is better that he or she should not have been born. The Mishnah says (Avot 1:17) that the main thing in Judaism is the action, not the learning.
