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 best translated as "not only...but also." After words implying sameness "as".

missing "look"  -- (MW) The untranslated word  "See!" and "Look!" It is from the most common word meaning "to see" in Greek. In a humorous vein, it is also an adverbial exclamation like we use the phrase "tah-dah" in a magic show, or "voila" in French. "Look!" or "See!" comes closest in English. Jesus uses it both ways.

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

missing "myself" -- (MW)  The pronoun "I" is used here.  When the subject of the sentence is part of the verb, this pronoun accentuates who is speaking "I." Saying "I myself" captures this feeling in English. The subject pronoun repeats the information in the verb so it should be repeated in English like "I myself." When it has no verb, the verb "is" or the previous verb is assumed. 

am going to -- This is not the future but the present tense. 

send -- (CW) "Send" is an uncommon verb that means  to "dispatch", "send forth", "send away", and "dismiss."  It is a more complicated form of the word that means "send" from which we get our word, "apostle." Its primary meaning of "dispatch" works well in this context because it refers to a message. This is not the word usually translated as "send." 

you -- (IW) This word is not in the Greek source. 

what -- (IW) This word is not in the Greek source. 

my -- "My" is the first-person possessive singular pronoun.  This word follows "father" and would be more accurately translated as "of mine".

missing "the/this"  -- (MW) The untranslated word is the Greek definite article," the," which usually precedes a noun or changes the word it precedes (adjective, infinitive, participle, etc.) to act like a noun. The Greek article is much closer to our demonstrative pronouns ("this," "that," "these," and "those"). See this article for more. 

Father -- "Father" is the Greek noun that means "father" or any male ancestor so "forefathers". It is the word that Christ uses to address his own Father. 

has -- (IW) This word is not in the Greek source. IW - Inserted Word-- The "has" doesn't exist in the source.

missing "the"  -- (MW) The untranslated word   "the" is the Greek definite article, "the," which usually precedes a noun or changes the word it precedes (adjective, infinitive, participle, etc.) to act like a noun. The Greek article is much closer to our demonstrative pronouns ("this," "that," "these," "those") than the English "the." See this article for more. 

promised --  (WF) "The promise" is a Greek word that Jesus only uses twice that means "command", "summons", "announcement", "notice", " offer", "promise", "profession", and "undertaking." The verb root means  "to announce." It is a more complicated form of the word that is translated as "angel", which actually means "messenger".  With the word "dispatch," the sense is "announcement". This is not a verb but a noun.. 

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

upon -- The word translated as "upon" means "on", "over", "upon", "against", "before", "after", "during", "by" or "on."  Since the context is carrying a message, the sense is "by" or in English we would say "with".

you -- The "you" here is the second-person, plural pronoun in the form of an object.  

but -- The Greek word translated as "but" means "but", "however", and "on the other hand". Since it always falls in the second position, translating it as "however" often captures its feeling better. 

stay -- (CW) "Stay" is a Greek verb that means  "to make sit down", "to seat", "to place", "to sit", "to post", "to take seats", "to convene", "to appoint",  and "to establish". This is word not usually translated as "stay."  

missing "you"  -- (MW) The untranslated word  "you" is used explicitly as the subject of the sentence. When it has no verb, the verb "is" or the previous verb is assumed. When it is already part of the verb, its use here creates emphasis on the "you" as we might say "you yourselves." It sometimes precedes a verbal adjective or infinitive where it is not part of the verb. It is plural. 

missing "yourselves"  ---- (MW) The pronoun is used here explicitly as the subject of the sentence. Since this information is already in the verb, the sense is repetitive as we say "you yourselves."  

in -- The word translated as "in" also means "within", "with," or "among."

the  -- The word translated as "the" is the Greek definite article, "the," which usually precedes a noun or changes the word it precedes (adjective, infinitive, participle, etc.) to act like a noun. The Greek article is much closer to our demonstrative pronouns ("this," "that," "these," "those") than the English "the." See this article for more. 

city -- The Greek word for "city" meant not only a city but a nation, culture, or a society. It worked something like the word "community" today.

until -- The word translated as "until" means "until" but it also means "in order that."  The form of the next word affects how it can be translated.

missing "this"  -- (MW) The untranslated word  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. In the form it is here, the meaning is "for this" so the previous word translated best as "in order for this." The next phrase is the dependent clause.

you -- This is from the second-person, plural form of the verb.

 have been  -- (WT) The helping vcrb, "will," is needed to show the future tense of the verb. 

been -- (WV) This helping verb "be" seems to indicate that the verb is passive but it isn't. It is a verb form that indicates the subject is acting on itself.  

clothed --  The word translated as "clothed " is a verb that means to "go into", "put on [clothes]", "enter", "press into", "sink in" and so on. Jesus mostly uses this word in the context of clothing, where it means "put on" and that works here as well. However, the form is the subject acting on themselves, so "put on yourselves". The tense is likely the future, but it could be the tense that indicates something happening at a point in time, nut then the mood would indicate a possibility not a certainty.

with - This completes the meaning of the verb. It is from the prefix.

power ---"Power" is a word that describes abilities and capacities, what actions a person can do or has done so "power", "might", "influence", "authority," and "force." It does not carry the sense of authority over others, either people or laws. The verb form of this word is translated as "can" in the NT.

from -- The Greek preposition translated as "from" means "out of" or "from." In Greek, they use the genitive case instead of a preposition for the types of phrases with usually use with "of."

on -- (IW) This word is not in the Greek source. 

high-- "High" is another word that Jesus only uses here. It  means "height" and metaphorically, "summit" and "crown". As an adjective, it means "sublimity", and "grandeur." In English, we might say "above."
