apparent style is a concentration on atonement for uncleanliness and sin, particularly via rituals involving "wave offerings". In textual criticism, the laws attributed to this writer are seen as having formed an earlier independent collection of laws, which were later added to the Priestly Code by an editor, and may, slightly, pre-date the Priestly Source. Another set of distinctive colophons are those of the form this is the law of [subject A], and [subject B], and [subject C], ...., which occur for Leviticus 7:28-38, 11:1-47, 13:47-59, 14:33-57, and 15:1-31. Of these, Leviticus 15 is noticeably repetitive, repeating both bathe [itself] in water and be unclean until the even, for almost every verse, as well as the detail of the atonement sacrifice. This chapter is therefore, under academic criticism, viewed as a late expansion of an earlier, much shorter, law, which simply laid out the basic rule that running issue of bodily fluids is ritually unclean, and contact with it, including with the person that possesses it, is ritually unclean, rather than detailing the atonement sacrifice, and listing examples of what constitutes contact. Another of these, Leviticus 11, which defines and lists animals which are ritually unclean, also provides an extensive list. Several of the laws appear very similar to those given on the subject in Holiness Code, and thus several critics infer that this chapter is a later expansion of the Holiness Code. Other critics view the chapter as an excerpt from a further once independent body of teaching, a view not completely incompatible with those who see it as ultimately being based on the Holiness Code. The relationship of Leviticus 15, and the other, less list-like, sections having the same style of colophon as Leviticus 11, to this supposed earlier body, is not generally agreed upon. However, even if they are part of this earlier collection, it is generally considered that each appear be based on laws from different periods of history to one another, since some, such as Leviticus 14:33-57, include less naturalistic rituals for transferring sin, and others, such as Leviticus 15 prefer a ritual of atonement, and yet others, such as Leviticus 13:47-59 do not mention atonement at all. Another distinct style is that of case law, in which the basic outline of a brief problem is described, such as Leviticus 15:32-41, discussing how to deal with a man who has collected sticks on the sabbath,
