DEUT260 The Talmud (Chagigah 9b) records that there is absolutely no comparison between he who has reviewed a Torah passage 100 times and the person who has reviewed it 101 times! The verb used for teaching in the Torah and the noun in the Talmud reflect the need for review. When the Torah says [this verse] "you shall teach," the word veshinantam actually means "you shall double" or you shall teach a second time, from the Hebrew word sheni (two). Similarly, the word mishnah technically means "that which is studied twice," indicating the importance of review. The Midrash (Vayika Rabbah 19:2) has already addressed this apparent difficulty of someone who sees how much Torah there is to learn and who seems overwhelmed and will not even try because of the enormity of the task. It says that the fool looks at the enormity of it all and gives up, but the wise person says I will learn two short passages today, two tomorrow, until I finish the entire book. If, each day, a person learns a small amount, over the course of a lifetime the person can become a Torah scholar. The Talmud says (Megillah 28b) that he who studies a few laws daily is guaranteed a place in the world to come. Although no one can possibly learn and retain everything, one must make the attempt to try. As the Mishnah (Avot 2:21) says, one need not complete the task, but neither is one exempt from trying.
