The Rambam writes in Hilchos Channukah Perek 4 Halacha 12:
אפילו אין לו מה יאכל אלא מן הצדקה שואל או מוכר כסותו ולוקח שמן ונרות ומדליק
What is the reason the Rambam wrote to take "Shemen and Neros" to light? Seemingly he could have just written "Shemen" or "Neros".
It was recently pointed out in a question/answer the shita of the Evnei Nezer that there is a din "cli" by the Channukah candles. Perhaps this Rambam is coming to also say that one needs to use a cli.
