After Odysseus is given the bow, what does Telemachus command Eurycleia to do and why?

He commands Eurycleia, ‘Wise Eurycleia, Telemachus orders you to shut the hall doors tight, and if any of the women hear men shouting or groaning in here, they are not to rush out, but to stay where they are and silently carry out their tasks.’

Telemachus wants none of the suitors to be able to escape the hall once his father strings the bow.
