there --The word translated as "there" means "there" or "in that place" but it also means "the intelligible world," that is, the world we understand.

see -- (CW, WV) "Shall see" is a verb that means "to see," "to behold," "to look," "to aim at," "to look towards," and similar meanings. It is not one of the common words for simply saying"see." Jesus uses this verb in a specific way,  in the future tense and the middle voice. The middle voice means that the subject is acting for or by themselves so "will behold for yourself." However, it also has the same root as the Greek word "eye," so "will behold with your own eyes" comes the closest. It is a light-hearted way to make a promise about the future.

missing "yourself"-- (WV) A phrase is necessary because the form of the previous verb is a middle voice, which means that the subject is to  act on "yourself," "for yourself" or "by yourself."

prophets, -- (UW) The Greek word translated as "prophets" means "one who speaks for God," "interpreter" and was the highest level of priesthood in Egypt, but its root words mean "shine light before" and so "luminaries," "shining lights" or "enlightened" seems to capture the idea better. Jesus uses it to refer not only to divine spokespeople but their books in the OT.   It is an untranslated Greek word adopted into English. It means "one who speaks for God", "interpreter" and was the highest level of priesthood in Egypt. It does not mean "one who sees the future" as it does in English. The sense is more a "luminary" because the Greek word comes from "light shining." Read this article for more information.

kingdom -- The word translated as "kingdom" can be the region, the reign, the castle or the authority of a ruler.

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.
