hidden that will not be disclosed, and nothing concealed that will not be known or brought out into the open.

For -The word translated as "for" introduces a reason or explanation so "because" and, in questions, "why." However, since this word always appears in the second position, it is more like an aside remark like, "consequently" or "as a cause."

there -- This is from the third-person, singular form of the verb.

is -- The verb "is" here is the common form of "to be" in Greek. It means to have a certain characteristic or remain in a certain condition. It also equates terms or assigns characteristics.  The word also means "to exist" and where it doesn't connect to characteristics or conditions.

nothing - (CW)  The Greek word translated as "nothing" is the Greek negative used to deny objective facts, not opinions. It means "no," "not," or"no truly." It makes a negative statement of fact. When a negative precedes the verb, it affects the whole clause. When it precedes other words, its force is limited to those words. This is not the word usually translated as "nothing."

hidden ,  -- (WT) "Hidden" is from a verb meaning   "to hide," "to cover," "to conceal." "to keep secret," "cover in the earth," "bury," and "conceal."It is in the form of a participle. This is in the present tense, "hiding."

that -- The word translated as "that" is a demonstrative pronoun ("this" "that"), but it often acts as a pronoun, "he," "she," "it," "which," "what," "who," "whosoever," "where," "when," "for which reason," and many similar meanings.

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

not  -- The Greek word translated as "not" is the Greek negative used to deny objective facts, not opinions. It means "no," "not," or"no truly." It makes a negative statement of fact. When a negative precedes the verb, it affects the whole clause. When it precedes other words, its force is limited to those words.

be -- (WV) This helping verb "be" indicates that the verb is passive. Helping or auxiliary verbs are needed to translate the Greek verb forms into English.

disclosed-- (WW) The word translated as "disclosed" means "to become," that is, to enter into a new state. When applied to events, this word means "to happen," "to occur," or "take place." For things, it can be "to be produced." When the participle takes a predicate, the sense is "coming into" something. The form of the verb's object can indicate the time or to whom it "happens." This is not the specific meaning of the word in this situation. \

missing "visible"  -- (MW) The untranslated word  is from an adjective that means "visible", "manifest", "shining", "illustrious", "conspicuous," and "open."

and -- (WW)The Greek word for "and" is an adverb that means "not at all" or "not even" and, literally, "not, however." As a conjunction, it works as both parts of the "neither/nor" constructions.

nothing  -- (IW) This word is not in the Greek source.

concealed , -- "Concealed " is an adjective that means "hidden", "concealed", "underhand", "unknown",  "obscure", "recondite", and "hard to understand".

that -- The word translated as "that" is a demonstrative pronoun ("this" "that"), but it often acts as a pronoun, "he," "she," "it," "which," "what," "who," "whosoever," "where," "when," "for which reason," and many similar meanings.

will -- (WW) This helping verb indicates that the verb is the future tense, but it isn't. It is in the form of possibility so it needs a "should" or "might."

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.

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

known -- "Known" is a verb that means  "to learn to know,""to know," "to recognize," "make known," "to know carnally," and "to learn." The idea of "learn" seems to translate this word better so it isn't confused with the verb meaning "have seen" which is also used to mean "know." This verb is more versatile because it can be used in more tenses.

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."

brought -- (WW) The word translated as "come" primarily means "to start out" but Christ usually uses it to mean "come" but not always. It indicates movement, especially its beginning, without indicating a direction toward or away from anything, so it works either as "start," "come," or "go," but it is more like our phrase "being underway." Our English word "show up" captures both the "start" and "come" ideas. See this article for more. 

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

into -- The word translated as "into" means "into" a place, "towards" as a direction, "in" (a position),  "as much as (of measure or limit)," "in regards to" a subject, "up to" limits in measures, "until" in reference to time, "within" a time limit, and "for" a purpose or object.

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

open. -- "Open" is from an adjective that means "visible", "manifest", "shining", "illustrious", "conspicuous," and "open." This translation is inconsistent in this verse, translated as "manifest" elsewhere here.
