KJV — word by word

Blessed -- (CW) The word "blessed" in Greek is an adjective from a root word meaning "happy" or "fortunate". In Jesus's era, all luck was attributed to divine favor but this is not otherwise a religious word. It has no relationship to the Greek verb "bless" or the noun "blessings".

are -- There is no verb "are" in the Greek source. It is implied by the equating of "workman" with "worthy" both in the Greek form of subjects.

they -- (CW) The word translated as "they" 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. 

which do -- (IP) There is nothing that can be translated as "which do" in the Greek source.

hunger --(WF) The word for "hunger" is the verb for "to hunger" as in needing food and, like the English word, it is a metaphor for any craving. However, unlike the English verb, this Greek verb is transitive like our "crave".  It is in the form of an adjective that, with the article, has the sense of, "the ones hungering".

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

thirst -- (WF) The Greek word for "thirst" is again a verb and very like our English word, "to thirst", meaning "to feel thirst", "to be parched" and "to thirst after" a thing. However, unlike the English verb, this Greek verb is transitive like our "crave".  It is also in the form of an adjective used as a noun, "the ones thirsting".

after -- This is needed in English because our verbs are not transitive, that is, taking a direct object but the Greek words do.

righteousness: -- The word translated as "righteousness" carries the sense of virtue but specifically that of fulfilling legal or social requirements. This ties it to the idea of fulfilling the law. We use the term "justice" more commonly today. This refers to natural law and the traditions of custom rather than to governmental laws. It does not mean conforming to current social fashions in thinking, which are seen as its opposite. When applied to God, it works best as "justice", but when applied to people "virtue" works better since we don't use "righteousness" much anymore.

for -- The "for" here is a causal adverb that means "seeing that", "because" or "since."

they -- This is from the third-person, plural form of the verb.

missing "themselves" -- (MW)  The subjective pronoun repeats the information in the verb so it should be repeated in English like "they themselves".

shall -- This helping verb "shall" 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.

filled. -- The Greek word translated in this version as "filled" also means "to satisfy" with a close association with the physical satisfaction of eating. Jesus uses a bit of humor here, choosing a word that is usually applied to cattle, specifically the fattening of cattle. There is another potential take that may or may not work, that is, interpreting this as "get their fill".
