Final answer:
In chapter 13, the intended victim is not murdered; instead, the assassins mistakenly wound each other and kill their guide, an old woman.
Step-by-step explanation:
The student has asked how the person is murdered in chapter 13 of an unspecified text. From the context given, it appears that the murder is fictional and possibly from a story set in medieval times. As described, assassins break into a room intending to kill a boy, but instead, they inadvertently wound each other and kill the old woman who acted as their guide. This chaotic scene is part of a larger narrative where the boy later identifies himself as Gil-Dong. There do not seem to be any specific murders tied to the Bible verses and historical events quoted, but they may be referenced thematically in the narrative or may be unrelated to the specific nature of the murder in chapter 13.
