The Formatting rule includes the methods of writing consecutive paragraph or sentences. Just as a paragraph is a collection of sentences unified by a topic sentence and developed by supporting sentences, so too, a chapter very often has a theme that is developed by a skillfully sequenced set of paragraphs. Rashi knew of 3 methods of writing consecutive paragraphs
• Cause-effect: The second paragraph is the effect of the first paragraph. The first paragraph is the cause of the second paragraph.
• Contrast: The two paragraphs illustrate contrasting sides of a theem.
• Unified theme: The two or more paragraphs illustrate a common theme. For example a common theme may be illustrated by a sequence of paragraphs each of which exemplifies and illustrates the theme idea.
The above three principles indicate methods for paragraph development into chapters as well as method for sentence development into paragraphs.

We formerly classified paragraph and chapter development under the grammar rule. However we think it more proper to devote the grammar rule to the relation between meaning and form, for example how verb conjugational forms indicates meaning. As indicated above the formatting rule governs use of sequence to indicate climax and paragraph sequencing.

Rashi on Gn27-41a explains the sequence in two paragraphs/sentences indicating a cause-effect relationship.
• Gn27-41a And Esauv thought to himself: My fathers [death and subsequent] mourning period are close by and [only then, after his death]
• Gn27-41a will I kill Jacob my brother.

Advanced Rashi: Rashi's point is that My father whom I love is a deterrent to killing Jacob. I don't want to cause my father anguish by killing my brother, his son, during his lifetime. So I will wait till after my father's death to kill my brother. If we examine this Rashi closely we see that Rashi is seeing the first verse half - the death and mourning period for my father - as causing, or more precisely enabling, the second verse half - the murder of my brother.
