from the same time period not entered into the Mishnah were recorded as Baraitot (external teaching), and the Tosefta. Other traditions were written down as Midrashim. After continued persecution more of the Oral Law was committed to writing. A great many more lessons, lectures and traditions only alluded to in the few hundred pages of Mishnah, became the thousands of pages now called the Gemara. Gemara is written in Aramaic, having been compiled in Babylon. The Mishnah and Gemara together are called the Talmud. The rabbis in the Land of Israel also collected their traditions and compiled them into the Jerusalem Talmud. Since the greater number of rabbis lived in Babylon, the Babylonian Talmud has precedence should the two be in conflict. Orthodox and Conservative branches of Judaism accept these texts as the basis for all subsequent halakha and codes of Jewish law, which are held to be normative. Reform and Reconstructionist Judaism deny that these texts, or the Torah itself for that matter, may be used for determining normative law (laws accepted as binding) but accept them as the authentic and only Jewish version for understanding the Torah and its development throughout history.

Thus they hold that even as small a mark as a kotso shel yod (קוצו של יוד), the serif of the Hebrew letter yod (י), the smallest letter, or decorative markings, or repeated words, were put there by God to teach scores of lessons.

In a similar vein, Rabbi Akiva (c. 50 – c. 135 CE), is said to have learned a new law from every et (את) in the Torah (Talmud, tractate Pesachim 22b); the particle et is
