Moses vs Santa Claus

Santa Clause:
Sweet robes, Obi
Wan-too-days in the sun
stop preaching homie
teach your flock to covet some fun
I bring joy every year
man represent cheer
you represent sandals
and a scraggly beard
I'm from the North Pole
that's why my rhymes are so cold
I spit diamonds
but I'm serving up some fresh coal
you been a naughty boy
you brought a plague of frogs
