Certain Biblical paragraphs are stated in a Theme-Development form. In other words a broad general idea is stated first followed by the development of this broad general theme in specific details. The Theme-Detail form creates a unified paragraph and consequently the law or narrative statement only applies to the enumerated details but not to other cases. Today's example illustrates this as shown below.

Verses Ex12-46c discussing the requirement of eating the Pascal lamb: states
• General: It shall be consumed in one house
• Detail:
  • Don't take any meat outside
  • Don't break any [meaty] bones
The general clause states it will be consumed in one house and could mean that besides consuming the meat one must consume the marrow inside the bones. The detail clause provides specificity to the general clause and describes how it should be interpreted: Although you must consume all meat you need not break bones to expose the marrow and eat it.

Advanced Rashi: This Rashi is based on the Mechiltah which forms the basis for the Talmudic passages in Pesachim 85, 95. The Talmud adds complexity to the exegesis by bringing in an identical verse repeated in Nu09. The Talmud actually makes several inferences. My way of taking the Talmudic exegesis is as follows:
• Eat all meat of the Passover sacrifice (Ex12-08)
• But don't break bones to eat the marrow inside (Ex12-46c)
• Don't break bones with meat on the outside (since nothing should be leftover) (Nu09-12)
• It is permissable to break bones which neither have meat inside nor outside (General-Detail).
