There- -- (CW) The "therefore" is not from the usual word translated as "therefore" but from two words. The first is dia which means "through," "in the midst of," "in a line (movement)," "throughout (time)," "by (causal)," "among," and "between." With the accusative, it can also be "thanks to," "because of,"  "by reasons of," and "for the sake of."

-fore  - The second means "from there," "this [thing]," or "that [thing]." So the phrase means "through this," referring to the quote about the capstone (Matthew 21:42)and the parable of the tenants (Matthew 21:33).

I -- This is from the first-person, singular form of the following verb.

tell -- The word translated as "say" is the most common word that means "to say," and "to speak," but it also means "to teach," which seems to be the way Christ uses it more frequently. It also has many ancillary meanings such as "to count" ("to number" or like we might say, "to recount" a story) or "to choose for yourself." Christ usually uses this word to refer to his own speaking or teaching.

you,  -- The Greek pronoun "you" here is plural and in the form of an indirect object, "to you," "for you," etc.

, the -- The word translated as "the" is the Greek definite article. The Greek article is much closer to our demonstrative pronouns ("this," "that," "these," "those") than the English "the." See this article for more. 

kingdom -- The word translated as "kingdom" can be the region, the reign, the castle or the authority of a ruler. Christ does not seem to use it to mean a physical region, so its translation as "reign" or "realm" seems more appropriate. This is especially true because the "reign" of a king means the execution of his will.

of -- This word "of"  comes from the genitive case of the following word that requires the addition of a preposition in English.  The most common is the "of" of possession.

missing "the"  -- (MW) The untranslated word 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. 

God -- The word translated as "God" means "God" and "deity." It is introduced with an article, so "the God," "the Divine" or "the divine one." Jesus often uses it this way perhaps to indicate the one God as opposed to the pagan gods.

will -- This helping verb "will" indicates that the verb is the future tense. Helping or auxiliary verbs are needed to translate the Greek verb forms into English.

be -- This helping verb "be" indicates that the verb is passive. Helping or auxiliary verbs are needed to translate the Greek verb forms into English.

taken  - (WW) "Taken" is from one of Christ's favorite "multiple meaning" words. It is a verb that means "to raise up," "elevate," "to bear," "to carry off," "lifted" in the sense of "removed." Jesus uses this verb to refer to what will happen to "the son of man," which can apply either to his being raised from the dead or lifted up on the cross. It is not the word for "take."

away from  - The word translated as "from" means "from" in both location and when referring to a source ("by"). It also means "after" in time. All these meanings work here.

you, -- The word translated as "your" is a plural, second-person pronoun in the genitive case. This pronoun follows the noun so "of yours."

and -- 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 can be translated as "not only...but also." After words implying sameness "as."

given  - The verb translated as "given" means "to give," "to grant," "to hand over," "appoint," "establish," and "to describe." It is almost always translated as some form of "give." The form is future, passive, so the "shall" and "be" apply here.

to -- This word "to" comes from the dative case of the following word that requires the addition of a preposition in English. The most common is a "to" for the English indirect object.

a -- There is no indefinite article in Greek, but when a word doesn't have a definite article, the indefinite article can be added in English translation.

people - The word translated as "people " is almost always translated as "gentiles." This is one of the rare situations where it is translated correctly. 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. However, Christ uses it to refer to foreign nations, especially those ruling Israel.

who -- (IW) There is nothing that can be translated as "who" in the Greek source. It was added because the next verb was translated as active rather than a participle.

will  -- (WT) This helping verb "will" indicates the future tense, but the verb is not the future.

produce - "Produce " is from a verb that primarily means "make" but it usually translated as "do" in the NT. In the sense of "make" it means "produce," "bring into existence," "bring about," and "cause." Here, the sense is "producing."

its .  - The word translated as "its " is the adjective that is normally translated as "his, hers, or its." This word appears after "fruit" so "of it."

missing "the"  -- (MW) The untranslated word 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. 

fruits  - The word translated as "fruit" primary meaning is "fruit," "seed," or "offspring," but its secondary meaning is "returns," specifically, "profit," as we would say "fruit of our labors."
