This may say something more than is translated because there are several untranslated words here. There is also a unique word, as we usually see in Luke. There is also a very poetic phrase that is sadly lost in translation. This verse also demonstrates the problems in translating the Greek word word other ethnic groups.

The Greek word translated as "and" is used as the conjunction "and", but it also is used to add emphasis ("also"). In a series, it is best translated as "not only...but also." After words implying sameness "as".

"They shall fall" is translated from a Greek word that means "to fall" and "to fall down." It is the root word for dozens of Greek terms involving moving from a higher state to a lower one. Like our word "to fall" it has a number of special meanings including "to fall into a given class", "to prostrate", "to fall from power", "to perish," and so on.

The Greek word translated as "by the edge" is  means "mouth" and therefore, "speech" or "utterance." However, it also means the "face" or "front" of something. With a weapon, it means "point" or "edge", which is very poetic, in a bloody kind of way. The image is of the weapon eating the flesh or drinking its blood. There is no "the" here. The "by" comes from the form of the word, which it usually an indirect object but has a number of other uses. Here it describes an instrument.

Next, the term for "of the sword" means a short sword, a weapon much more like a machete, since the Greek is the source for the English word "machete", via Spanish. It specifically the type of weapon used for making sacrifices, by assassins, bodyguards, and jugglers. Jugglers is particularly interesting because of the word "toss".

The Greek word translated as "and" is used as the conjunction "and", but it also is used to add emphasis ("also"). In a series, it is best translated as "not only...but also."  This is the second use so the sense is "but also".

"Shall be led away captive" is the unique word in this verse. It is also a very long word, which means to "take prisoner". It is so long because it is built up, starting with the simple verb for "take", which when lengthened, becomes the verb "capture", which when lengthened again become the noun "captive", which, when lengthened  into a verb again becomes "take prisoner. Was this humorous? Perhaps.

The word translated as "into" means "into" a place, "towards" as a direction, "in regards to" a subject, and "up to" limits in time and measure.

The word translated as "all" is the Greek adjective meaning "all", "the whole", "every," and similar ideas. When it is used as a noun, we would say "everything."

The word translated as "nations"  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. I translated it as "other ethnic groups" or "other ethnic areas".

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

The word "Jerusalem" denotes the city or its inhabitants. Two different forms of this word appear in the NT.  This version is used most heavily in Luke, mostly in his narration, but a few times in Christ's words. It seems to be the more formally Greek version of the name.

The verb "shall be" here is the common form of "to be" in Greek. It means to have a certain characteristic or remain in a certain condition. It also equates terms or assigns characteristics. It is not usually used as a "helper" verb like English "to be" is. To create a future form of a verb, Greek just adds the appropriate ending. So the use it is to say something more complicated than a simple future tense,

"Trodden down" is an uncommon verb, which means to "tread", "walk", "dwell in", "frequent", "tread under foot", and "trample on".   The form is also uncommon, a middle passive adjective. The sense is "being trampled down by itself", which is the form of an adjective.

The word translated as "of" primarily means "by", "under," or "with". Its primary meaning is "under" both in the sense of moving under, being under, and being under different forms of compulsion.  This is not a possessive form as translated, but nor does it mean "by"  in the sense of the ones doing the trampling. It merely indicates the position.

There is no "the" here. It is added because of the problem with the following word.

The word translated as "Gentiles" here is the same word translated as "nations" above.  Its primary meaning is "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.

"Until" is from another uncommon word that means "until", but unlike the more common word for "until", it also has the sense of "continually until".

There is an untranslated word here. It is a demonstrative pronoun ("this" "that"), but it often acts as a pronoun ("the one that), especially a connective pronoun ("the one that") introducing a dependent clause.  It is the object of the "until" so "until this".

There is no "the" here. It is added because in English, we always seem to add "the" before a plural. However, in Greek, adding it limits the word to a specific set of things. Leaving it out, leaves the following word unbound,

"Times" is a noun that means "due measure", "season", "opportunity", "time," and "profit." I like "opportunities" here. This is not the common word to indicate a period of time. Jesus uses "days" for that idea. This begins the phrase that ends the verse as a punch line. In the Greek, a lot more comes before it.

The word translated as "of the Gentiles" here is the same word translated as "nations" above.  Its primary meaning is "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. The "of" comes from the form, which can be a possessive.

"Be fulfilled" is a verb that means "to fill", "to fulfill," and "to fill full."  The form is not the future. The tense indicates something happening at some point in time. The form is "They are fulfilled". Since the verb comes far before the possible subject, the "they" is needed. This verb comes after the untranslated "this", before the phrase above.

There are  two untranslated words between the verb above and the ending phrase about the Gentiles.  They  are left out of the KJV and most other Bibles. They are shown in the order they appears after the verb.

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

The next verb is the common form of "to be" in Greek. It means to have a certain characteristic or remain in a certain condition. It also equates terms or assigns characteristics. The form is the future. When the verb "to be" appears early in the sentence before the subject, the sense is more like "it is" or, in the plural, "there shall be."
