What direction does Odysseus give to Telemachus regarding how they should behave and what they should do sinc they killed the suitor?

Is this in book 23? To make sure no one finds out about the murders, they will pretend Penelope's wedding to one of the suitors is occurring in the palace to give them time to flee to the woods.

Telemakhos and the others set up a fake wedding celebration. Penelope maintains her neutral attitude toward Odysseus and asks Eurykleia to make up his bed outside her bedchamber.
