What advice does Nestor offer Telemachus? Please help I’m in a rush

At Pylos, Telemachus and Mentor (Athena in disguise) witness an impressive religious ceremony in which dozens of bulls are sacrificed to Poseidon, the god of the sea. Although Telemachus has little experience with public speaking, Mentor gives him the encouragement that he needs to approach Nestor, the city’s king, and ask him about Odysseus. Nestor, however, has no information about the Greek hero. He recounts that after the fall of Troy a falling-out occurred between Agamemnon and Menelaus, the two Greek brothers who had led the expedition. Menelaus set sail for Greece immediately, while Agamemnon decided to wait a day and continue sacrificing on the shores of Troy. Nestor went with Menelaus, while Odysseus stayed with Agamemnon, and he has heard no news of Odysseus. He says that he can only pray that Athena will show Telemachus the kindness that she showed Odysseus. He adds that he has heard that suitors have taken over the prince’s house in Ithaca and that he hopes that Telemachus will achieve the renown in defense of his father that Orestes, son of Agamemnon, won in defense of his father.

Telemachus then asks Nestor about Agamemnon’s fate. Nestor explains that Agamemnon returned from Troy to find that Aegisthus, a base coward who remained behind while the Greeks fought in Troy, had seduced and married his wife, Clytemnestra. With her approval, Aegisthus murdered Agamemnon. He would have then taken over Agamemnon’s kingdom had not Orestes, who was in exile in Athens, returned and killed Aegisthus and Clytemnestra. Nestor holds the courage of Orestes up as an example for Telemachus. He sends his own son Pisistratus along to accompany Telemachus to Sparta, and the two set out by land the next day. Athena, who reveals her divinity by shedding the form of Mentor and changing into an eagle before the entire court of Pylos, stays behind to protect Telemachus’s ship and its crew.
