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

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

shall -- This helping verb "shall" indicates that the verb is the future tense or a form that indicates possibility at some time. A "might" or "should" could work here or nothing at all in an "if/when/whoever" clause which implies a possibility.  Helping or auxiliary verbs are needed to translate the Greek verb forms into English.

come -- (CW) The word translated as "shall come" is a complicated one because it indicates a "coming" that has been completed, that is, "to arrive" or, even, "to be present." As a metaphor, it means "to be a follower." Jesus seems to use it sometimes to mean "return." This is not the word usually translated as "come."

from --- The word translated as "from" means "from" in both locations and when referring to a source or a cause. It also means the instrument "by" which a thing is done and "away from." It is not the word form  usually translated as "of." Referring to time, it means "from," and "after."

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

east, -- The word translated as "east" primarily refers to the rising of heavenly bodies above the horizon. It comes to mean "east" because that is the direction in which heavenly bodies arise. However, it also refers to the sources of a river when it is in the plural as it is here.

north, -- The word translated as "north" is not the common ancient Greek word for "north" but it is used in modern Greek. The common word for "north" actually means "north wind" or the direction of the north wind. There is no article used, so not "the north" but simply "north" as a direction.

sit -- The word translated as "sit down" means to "lean against" or "to be made to recline" by someone else, but here it is in the passive. In that form, it means "to recline" and "to sink" by oneself. Of course, at the time, people reclined to eat, but the sense of sinking below the patriarchs is part of its meaning.

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

in -- The word translated as "in" means "in," "on," "within," "with" (an instrument), "by" (near), "by" (means of), "during" (time),  or "among"  with an indirect-object form object.  About time, it means "during the time," "in the time," "within," and "in." With the direct object form, it means "into," "on," and "for." When referring to time, it means "during." It can mean "on," "at," or "by" in the sense of "near."

the -- The word translated as "the" 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. 

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 comes from the genitive case of the following word(s) that required the addition of a preposition in English.  The most common is the "of" of possession, but it can also mean "belonging to," "part of", "which is", "than" (in comparisons), or  "for", "concerning" or "about" with transitive verbs. 

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." Jesus often uses it this way perhaps to indicate the one God as opposed to the pagan gods.
