"[d]eep as you are, my friend, you'll find it hard to plumb the plans of the everlasting gods." who says this and why?

Penelope was the one who spoke this, she said it when a nurse who said that the beggar who killed the suitors was Ulysses. Penolope, unbeliever said "Deep as you are, my friend, you'll find it hard to plumb the plans of the everlasting gods."

Explanation:

When he stepped on Ithaca, Athens disguised Odysseus as a beggar, so that his wife's suitors could not recognize him. The next day, Odysseus in the presence of Penelope, without being recognized, confided that her husband was alive and tried to return to Ithaca. Penelope revealed to him that she could not stand the pressure of having to marry, and that the next day she would run a contest to choose one of her suitors as her husband. It would be a winner who could shoot an arrow with the bow of Odysseus, who was to cross the hole of twelve axes lined up on the ground.

The next day, none of the suitors got the arrow. It was when the "beggar" under the laughter of disapproval of the suitors asked to be allowed to participate in the race. Odysseus, authoritatively and effortlessly, threw the right arrow toward the axes. Then with Telemachus and his faithful servants he slew all the suitors and the traitorous servants. After that, a nurse who had recognized Ulysses tells Penelope that that beggar is Ulysses, but Penelope unbeliever says "Deep as you are, my friend, you'll find it hard to plumb the plans of the everlasting gods."
