On this point, Ronald Witherup gives the example of Genesis 1-2, which most scholars view as two separate stories of creation written by different authors in different time periods. "Most biblical scholars accept Genesis 1 as originating around the sixth century B.C. with a group of scribes who were concerned about the preservation of the liturgical traditions of the Jews (thus the concern for the seven-day schema of creation and the notion of the sabbath). Genesis 2, on the other hand, originates from an earlier, more primitive tradition dated to around the tenth century B.C."
