The term "exorcism" means the action of exorcizing or expelling an evil spirit by adjuration or the performance of certain rites. In Jesus" case this involved His authoritatively commanding a demon or demons to depart with no appeal to a higher authority or incantations, which are common in exorcisms that other people perform.

"The contrast between the glory of the Transfiguration and Jesus" disciples" tawdry unbelief (see Matthew 17:17) is part of the mounting tension that magnifies Jesus" uniqueness as he moves closer to his passion and resurrection." [1][source]
It also recalls Moses" experience of descending Mt. Sinai only to find the Israelites failing by worshipping the golden calf ( Exodus 32:15-20). [source][source][source]
