4Q158 is grouped with 4Q364-7, and together are called the Reworked Pentateuch. 4Q158 contains portions of Genesis, Exodus, and Deuteronomy.
Most lines are exactly as they appear in the Bible and some are extrabiblical.
In general, 4Q158 parallels quotes from the Pentateuch with minor additions. This may be true when considering the entire Reworked Pentateuch, but since 4Q158 largely consists of direct quotes from sections of Genesis, Deuteronomy, and Exodus, it by itself would not be considered a wild text. Emanuel Tov and other scholars have suggested that 4Q365 is another copy of 4Q158. A relationship exists between the two in that they both contain material from Exodus although the readable sections are different. Considering the large portion of unreadable material in both documents it is conceivable, although difficult to prove, that the two could be duplicates of each other.
