This verse has three unique words. It also has a clear punchline at the end. Comparing this verse to Matthew 20:25, this verse uses more common words though they are used uniquely by Jesus here, but this verse uses those words in more complex forms. This version, however, is more entertaining because of the ending.

"The kings" is translated from a Greek word which means a "king" or "chief."

The word translated as "of the Gentiles " means "a group of people living together," a nation, a tribe, or a cast of people. Later it came to mean "barbarous nations" similar to our idea of ethnic people. It is in the same form as the "them" above, so "to them" or "for them." The "of" comes from the form of the word.

"Exercise lordship over" is from a Greek verb that Jesus only uses here. It  means " to be lord or master of" and " "possession of," and "seize".  However, this is a common verb outside of the NT. In Matthew, Jesus adds a prefix to this word, making it a new form. This word is the verb form of word Jesus commonly uses as a noun.

The word translated as "them" is the Greek word commonly translated as third-person pronouns in English.   

The Greek word translated as "and" is used as the conjunction "and", but it also is used to add emphasis ("also").

The word translated as "they that " is the Greek definite article, which usually precedes a noun and, without a noun, takes the meaning of "the one."  Here, it preceded the adjective form of a verb, making it act like a noun. The Greek article is much closer to our demonstrative pronouns ("this", "that", "these", "those"). See this article for more.  The form is that of the subject of the sentence. 

"Exercise authority upon" is another verb Jesus only uses in the verse that means to "exercise authority", "have power", "exercise authority over" and "enjoy license".  The form is not that of an active verb but of an adjective, "exercising authority over". The form is that of the subject of the sentence. This word is the verb form of word Jesus commonly uses as a noun.

The word translated as "them" is the Greek word commonly translated as third-person pronouns in English.   

The term translated as "are called" is like our word "call" because it means both "to summon" and also "to name." The form is that of someone acting on themselves, so "calling themselves". Other people are not calling them this, but they are calling themselves. This word comes at the end of the verse and is its punchline.

"Benefactors" is a Greek noun that Jesus only uses here. It means " benefactor " and, as an adjective, "beneficent", and "bountiful." This word is also in the form of a subject.
