Why does "Moses" suddenly appear here? Could you explain the phrase "play the part like Moses"?

Rebecca

This is a bit of a word pun. Moses is known for parting the Red Sea, and creating a divide in the middle that allowed him to cross safely. The lyrics say "play the part like Moses," with the "part" here meaning "role." The lyrics do not mean the same "part" that means "divide" (the Red Sea), but it has still used been used here due to the same pronunciation. Ex: Moses parted the red sea. Ex: The actor played his part very well.
