It's in chiastic structure, with the center of the chiasm being the word "Joseph's". This is also in the middle of chapter 37, which is ¾ of the way through the book of Genesis. That makes for a perfect cross. Joseph is the focal point of the chiasm because he was a type of Christ. Every section of Scripture is followed by one line of commentary. My next two books, Exodus and Leviticus, have two lines and three lines of commentary for every section of Scripture. This is supposed to make the shape of a sword. Some of the lines of commentary on either side of the chiastic center may appear to repeat themselves. This is simply the two sides of the cross, or chiasm, reflecting each other.
