This verse was spoken in a way to create suspense because its punch line, that is, a key word is saved until the end, This suspense is moved to the middle of the sentence so that ithe sentence reads more easily, but that destroys its suspense. Another hidden element here is that the negative in "no sword". It is the negative of thought and desire. And it doesn't apply to "the sword" but to "having". 

The Greek word translated as "but" denotes an exception or simple opposition. It is used to emphasize the contrast between things like we use "rather". It is the Greek word "other" like we use "otherwise".

The Greek word translated as "now" \means "now", "at the present moment","presently," and "as it is."

The word translated as "he that" is the Greek definite article, which usually precedes a noun and, without a noun, takes the meaning of "the one." The Greek article is much closer to our demonstrative pronouns ("this", "that", "these", "those"). See this article for more. 

The word translated as "hath" means to "have", "possess", "bear", "keep close", "have means to do",  "to have due to one", or "keep" and so on. It isn't an active verb, but in the form of an adjective, "having" as in "the one having".

The Greek word translated as "purse" here means "bag", "pouch", and "purse." This word is used in Luke 10:4, but not in similar verses in Matthew. It doesn't mean a money purse specifically, but any kind of bag. Though Matthew 10:9 has the word "purse" in English translation, the Greek word in that verb means "belt", which is where money was put during the era.

"Let him take" is one of Christ's favorite "multiple meaning" words. It is a verb that means "to raise up", "elevate", "to bear", "to carry off", "to take and apply to any use," and "to cause to cease." The sense here is "take up", but the form is a third-person command, a form we don't have in English. The sense is "he must take up" or "let him take up".

There is no "it" here, but earlier objects in a Greek sentence (here "a purse") can be assumed to be the object of later transitive verbs with repetition or a pronoun.

The Greek word translated as "and" is used as the conjunction "and", but it also is used to add emphasis ("also"). However, this "and" appears after the following adverb "likewise", not before.

The word translated as "likewise" is an adjective that means "like", "resembling," and "matching."  As an adverb, the form here, it means "likewise", "similarly" and so on.

There is no "his" in Greek.

"Scrip" is translated from a Greek word specifically meaning a leather pouch to carry food or provisions for traveling. We might call this a knapsack or provisions bag.

The Greek word translated as "and" is used as the conjunction "and", but it also is used to add emphasis ("also"). However, this "and" appears after the following adverb, not before.

The word translated as "he that" is the Greek definite article, which usually precedes a noun and, without a noun, takes the meaning of "the one." The Greek article is much closer to our demonstrative pronouns ("this", "that", "these", "those"). See this article for more. This begins a phrase that repeats and earlier pattern.

The word translated as "hath" means to "have", "possess", "bear", "keep close", "have means to do",  "to have due to one", or "keep" and so on. It isn't an active verb, but in the form of an adjective, "having" as in "the one having".

The negative "no" used here is the Greek negative of a subjective opinion, commands, and requests. The sense is that "you don't want" to do something, not that it isn't done or don't think something that might be true. It doesn't come before "sword", which actually appears at the end of the sentence. It comes before "having", so the sense is "the one not wanting to have".

There is no object of "having" here. This is clearly intentional in order to create suspect. The listeners expect an object for "have" especially from the earlier pattern in the sentence. The suspense created by its absence is particularly strong because they would be curious what someone wouldn't "want to have", since not wanting to have is rarer than not having.

The word "sword" is the last word in the verse. Its punchline. Listeners would expect it here but they are intentionally frustrated so it can be a surprise at the end of the verse. The term for "sword" specifically means a short sword, a weapon like a machete, since the Greek word used here is the source for the word "machete." Jesus seems to use "the sword" as a symbol for struggle, which is n necessary. Christ says explicitly that his larger purpose is not to bring peace but the sword in Matthew 10:34. 

"Let him sell" is a word that means "to sell" and "to exchange." When this word is applied to people (as it is metaphorically here), it means "to betray" or "to give up."

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

The word translated as "garment" means an outer garment ("a cloak"), like we would use a coat or jacket today. This quality of this garment was how people judge social status.

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

"Buy" is an uncommon verb that means "to occupy a marketplace", "to buy in the market," and "to buy for oneself." The form is again a third-person command, a form we don't have in English. The sense is "he must buy" or "let him buy". 

There is no "one" here. This is where the word "sword" appears at the punchline.
