What is Melanthius ordered to do in order t make the bow easier to bend?

In Homer's "Odyssey," Melanthius is ordered to fetch weapons and tools to help make Odysseus's bow easier to bend. Specifically, he is instructed to bring oil to grease the bow, which will facilitate its bending and enable Odysseus to string it successfully during the contest. This task underscores Melanthius's role as a servant in the palace, reflecting his allegiance to the suitors rather than to Odysseus.
