Yet -- (WW) The Greek word translated as "yet" means "but," "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.  It can also be an explanation of cause ("so").

because -- The word translated as "because" introduces a statement of fact or cause, "for what," "because," "since," and "wherefore."

I -- The pronoun "I" is used here. Since, as the subject of the sentence, it is part of the verb, its explicit use accentuates who is speaking "I." Saying "I myself" captures this feeling in English.

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

tell -- The word translated as "tell" is the most common word that means "to say," and "to speak,"  but when used with an objective noun or pronoun, the sense is "tell" or "speak of."  When two accusative objects are used, the sense is  "say of him this," or "call him this." The form Jesus uses to describe his own speaking can be either indicative, "I say/tell" or subjunctive, "I should/could say/tell."  It also has many ancillary meanings such as "to count" ("to number" or like we might say, "to recount" a story) or "to choose for yourself." Christ usually uses this word to refer to his own speaking or teaching.

the -- The word translated as "the" is the Greek definite article, without a noun, it has the sense of "the one." The Greek article is much closer to our demonstrative pronouns ("this," "that," "these," "those") than the English "the." See this article for more. 

truth,   -- The literal meaning of the Greek word for "truth" is "not hidden," and it means what is real as opposed to how things seem. Applied to people, it means "truthfulness" and "sincerity." The opposite of a lie or appearance.

you -- This is from the second-person, plural form of the verb.

do -- This English helping verb is used to create questions, commands, negative statements, and smooth word flow in translation from Greek

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. Adding "really" to the sentence captures the same idea. When a negative precedes the verb, it affects the whole clause. When it precedes other words, its force is limited to those words.

believe -- The Greek word translated as "believe" does not apply to religious belief as much as it does trusting in other people, especially their word. Christ usually uses it in contexts, as the one here, that apply to trusting words. The negation of "belief" with the objective, instead of subjective, negative, equates trust with a fact.

me -- The "me" is in the indirect object form on the first-person pronoun, so usually "to me," though the form has other uses in Greek.
