What does Athena instruct Odysseus to do now that he is in Ithaca?

When Odysseus returns to Ithaca from his voyage at sea, he is disguised as a beggar and lives with Eumaeus, the swineherd. Odysseus then must win the contest of strining a bow and shooting an arrow through axe-heads that Penelope set up. After he has done this, he must battle his wife's suitors and reclaim his spot as king.
