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 Nu09-02a discussing the requirement to observe the Passover states
• General: Let the Jews observe the Passover
• Detail: at its appointed time.
The general clause states Let the Jews observe the Passover and could mean that similar to allowing courts to change the exact date of the new month, the Jews can approximately observe Passover on the 14th, moving it a day or two forward or backward if it is necessary to avoid a great inconvenience (like Passover falling on Saturday). The detail clause provides specificity to the general clause and describes how Passover should be interpreted: It must be observed in its appointed time, the 14th of the month, even if it falls out on the Sabbath or while Jews are in ritual impurity which is very inconveniencing.
