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. 

Heaven -- The word translated as "heaven" means sky, the climate, and the universe. It also meant the home of the gods in a physical sense: the sun, moon, and planets were named for the gods. More about the word in this article.

and -- The Greek word translated as "and" is used as the conjunction "and", but it also is used to add emphasis, "even", "also" and "just".

earth --The word translated as "earth" means the physical planet, not society, which Christ describes as the world. See this article for more on these words.

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

pass away -- The phrase "pass away" is from a verb that means "go by", "pass by", "outstrip" (in speed) and "pass over". The form is the future tense. The sense here could be "pass by", "surpass", but the sense of "pass away" as in "die" is not at all clear. The word means to pass the time and can refer to times past, but it also means to "outwit" and "elude" and "be superior". It also means to "pass by" a place or to "arrive" at a place. In the Latin Vulgate, this verb was translated as transient which is the future, plural, active form of the transit, which means "to cross". In Greek, the form is neither active nor passive, but the middle form which means that the subjects are acting on themselves

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

missing "these"  -- (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. 

my .-- "My" is the first-person possessive singular pronoun, "my", "me" and "mine". Usually follows the noun so, "of mine".

words -- (CW) "Words" is translated from a Greek word that means "calculation" or "reasoning", but it has many, many specific meanings from "deliberation", "question", "subject matter", "narrative" and so on.  It is the source of our word "logic" and is the root word for all the English words that end in "-ology." Most biblical translations translated it as "word" for somewhat poetic reasons. However, when applied to people, it means "repute" or "reputation". More about this word in this article. In English, we would say "logic", "concept" or "reasoning" to describe it but it also means the communication of various types, so "message" often works. "Teaching" might work but it is unrelated to the common words for "to teach", "teacher" and "student" that all have the same root.

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

not -- (CW) The "not" here is both of the Greek negatives used together. Greek has two negatives, one objective, one subjective. The use of both together is more extreme, like saying, "never" or literally, "you cannot really think". When a negative precedes the verb, it affects the whole clause. When it precedes other words, its force is limited to those words. 

pass away -- The phrase "pass away" is from a verb that means "go by", "pass by", "outstrip" (in speed), and "pass over". The form is the future tense. The sense here could be "pass by" or "surpass", but the sense of "pass away" as in "die" is not at all clear. The word means to pass the time and can refer to times past, but it also means to "outwit" and "elude" and "be superior". It also means to "pass by" a place or to "arrive" at a place.
