Interesting and Hidden Aspects: 

The the original Greek says that a man and woman are "yoked" together for a purpose, that they have work to do together. They are two halves of the same thing. However, while the first part of the verse is about power, the second half is about opinion and how people think, not what they do.

"So that" is from an adverb that marks the power or virtue by which one does a thing. At the beginning of a sentence, it marks a strong conclusion.

The Greek word for "two" means "two" but it was also used to mean or a "couple," which is its sense here.

The Greek word translated as "but" denote an exception or simple opposition meaning "except", "yet," "rather," and "nay."

As in English, the word "one" can be used as a pronoun, meaning a single person.

The Greek word translated as "the flesh" means "flesh", "meat," and "the physical order of things" as opposed to the spiritual.

The word translated as "what" is a demonstrative pronoun, but it often acts as a pronoun, especially a connective pronoun introducing a dependent clause. This is the object of the verb.

The Greek word translated as "therefore" either emphasizes the truth of something ("certainly", "really") or it simply continues an existing narrative.

"Joined together" is from a verb which means "yoke", "harness", "bond fast", "join together," and "pair."

The "let" comes from the form of the verb translated as "out asunder" which is a command in the third person, which in English, we translated as with a "let."

The negative "not used here is the Greek negative of a subjective opinion. The sense is that "you don't want" to do or "don't think" something, not that it isn't done or real. If it was a statement of fact, a different negative would be used.

The Greek word for "man" in the singular means "person" and "humanity" and "people" and "peoples" in the plural.

The word translated as "put asunder" means to physically "separate," or "divide," but is also means to "separate in thought," and "distinguish." Christ only uses this word here and in the parallel verse in Mark. Everywhere else he uses another word to mean "divide" in the sense of severing. We assume this is because of the "separate in thought" meaning.
