But --  The Greek word translated as "but" denotes an exception or simple opposition. It is used to emphasize the contrast between things like we use "instead," "but instead,"or "rather." It is not the common word usually translated as "but." It is the Greek word "other" like we use "otherwise." Jesus often uses this conjunction to connect a negative clause, not doing something, with a positive one, "instead do this."

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

I -- This is from the first-person, singular form of the verb.

said   - The word translated as "said" means "to say" and "to speak." It is one of the two most common words translated "speak," "say" and "tell," but it has more a sense of addressing and proclaiming. The tense isn't a part tense, but one where something happens at a point in time, past, present, and future.

to -- This word "to" comes from the dative case of the following word that requires the addition of a preposition in English. The most common is a "to" for the English indirect object.

you,  --  The "you" here is from the plural, dative, second-person pronoun.

missing "the"  -- (MW) The untranslated word "that" introduces a statement of fact or cause, "for what," "because," "since," and "wherefore."

missing "also"  -- (MW) The untranslated word "also" is used as the conjunction "and," but it also is used to add emphasis ("also"). In a series, it is can be translated as "not only...but also." After words implying sameness "as."

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

have -- This helping verb "have" indicates that the verb is the tense indicating an action completed in the past.

seen -- (CW) "See" is from a Greek verb, which means "to see with the eyes," "to look," and "to observe." It is a metaphor for mental seeing, that is, perceiving. However, it is one of the many words that Christ uses to mean "see," but it is not one of the most common ones. Jesus often uses this word often to mean "watch out" or "look out" as a warning.

me, -- "Me" is the regular first-person pronoun in Greek as the object of the verb or preposition.

and -- The Greek word translated as "and" is used as the conjunction "and," but it also is used to add emphasis ("also"). In a series, it is can be translated as "not only...but also." After words implying sameness "as."

 still  - -- (IW) There is nothing that can be translated as "as" in the Greek source.

you -- This is from the second-person, singular 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. This is the present tense.
