The Talmud consists of 63 section
called tractates, which are divided into six orders. Each order deals
with a different subject . For example, the order Nashim (women)
discusses marriage, divorce, and other matters that concern
relationships between a man and a woman. Other orders cover such
subjects as religious feasts, and civil and criminal law.
According to Jewish tradition, the Mishnah originated in the time of
Moses during the 1200's BCE and was memorized and handed down from
generation to generation. Its contents were collected and written down
from about AD 70 to 200. The Gemara, which has two versions, was
written between about 200 and 500. The Palestinian Gemara was completed
about 425 and the Babyloninan Gemara about 500.
