tabernacle is the place where God speaks with the priesthood. Composition It is evident that rules of priestly procedure must have accompanied the institution of the priesthood, and in the earliest of times, before writing was invented, these rules probably were transmitted orally. When writing was first employed in connection with them, it is likely that only some general directions, or some details deemed most important, were committed to writing. As time passed on the importance given to written law would lead the priesthood to commit more and more of the details to writing. Critical scholars assert that in addition to this, over time, variations of detail would develop, authority for which must be committed to writing, so that actual practise would become justified by law. One would, therefore, suppose beforehand that such a code would exhibit evidence of gradual growth. Colophons, which, according to textual criticism, are best explained as survivals from previous collections, are found in parts of the priestly code, at Leviticus 6:7, 7:37-38, 11:46-47, 13:59; 14:54-57, and 15:32-33. Colophons generally occur at the end of sources, and it is for this reason that Biblical Critics assert that the priestly code is composed of several originally separate documents placed together, with these colophons marking the ends of some of the source texts. Aside from these colophons, and obvious breaks between laws, such as those caused by narrative elements, for example the break between Leviticus 7:31 and Leviticus 11:1, as well as those caused by the presence of the Holiness Code, it is more difficult to identify other potential borders between sources. One observation that can be made is that after each colophon, in Leviticus, there is a new introduction, of the form and the said unto Moses.... Several critical scholars have proposed that these introductions are an attempt to patch over the breaks between sources, and therefore conclude that everywhere there is a new introduction, there must be a break between sources. In addition to the colophons, and narrative breaks, this adds additional borders at Leviticus 4:1, 5:14, 6:1, 6:19, 6:24, 7:22, 7:28, 13:1, 14:33, and 15:1. More detailed textual criticism, comparing vocabulary, writing styles, and so forth, is seen, by critical scholars, to support the idea that both the colophons, and the introductions, mark the borders between works originating from different writers, except for Leviticus 6:1. Leviticus 5:15-19 and 6:2-18 are usually regarded, under textual criticism,
