Both Hebrew and Christian lectionaries developed over the centuries. Typically, a lectionary will go through the scriptures in a logical pattern, and also include selections which were chosen by the religious community for their appropriateness to particular occasions. The one-year Jewish lectionary reads the entirety of the Torah within the space of a year and may have begun in the Babylonian Jewish community; the three-year Jewish lectionary seems to trace its origin to the Jewish community in and around the Holy Land. The existence of both one-year and three-year cycles occurs in both Christianity and Judaism.
