Which -- The Greek word translated as "some" in the singular means "anyone," "someone,"  "something," and "anything." In the plural, it means "some," "they," and "those." Jesus often uses it to start a question so it means "who," "what," or even "why."

of -- (CW) The Greek preposition translated as "of" means "out of" or "from." The word also means "beyond," "on," "in," "since," or "by"based upon its context. However, in Greek, they use the genitive case instead of a preposition for the types of phrases that are translated into English "of" phrases.

you -- The word translated as "your" is a plural, second-person pronoun in the genitive case. This pronoun follows the noun so the possessive "of yours." Here, it is the object of the previous preposition. As an object of a preposition, the genitive indicates movement away or a position away from something.

convinceth   - (CW) "Convinceth " is from a verb from the word that means "to disgrace," "to put to shame," "to cross-examine," "to expose," and "to decide a dispute." Jesus only uses it four times and seems to mean "accuse."

me -- "Me" is the regular first-person pronoun in Greek as the object of the verb or preposition. As the object of a preposition, an accusative object indicates movement towards something or a position reached as a result of that movement.

of -- (CW) The Greek word translated as "of" means "around" when referring to a place, but in referring to a subject, it means "about," "concerning," "on account of," and "in regard to." This is the way Jesus usually uses it.

sin? -- (CW) The word translated as "sins" means "missing the mark," "failure," "fault," and "error." Only in religious uses does it become "guilt" and "sin," having no sense of doing malicious evil in Greek. The best English translation is "mistake," "fault," or "failure" rather than what we commonly think of as the evils of "sin." See this article for more information and context.

And -- (OS) There is nothing in the Greek that can be translated as "and" in the source we use today but it does exist in the source that the KJV translators used. However, it didn't mean "and" but something more like "however."

if -- The "if" here expresses a condition but it means nothing regarding whether that condition is met or not. It also means "if ever" and "whenever."

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

say -- The word translated as "say" is the most common word that means "to say," and "to speak,"  but when used with an objective noun or pronoun, the sense is "say of" 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 -- (IW) There is nothing that can be translated as "the" in the Greek source.

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.

why--  (CW) This "why" is not a common way to ask "why" in Greek. It is two Greek words, meaning literally "thanks to something" or "because of something". The preposition means, with the accusative object used here, "thanks to," "because of,"  "by reasons of," and "for the sake of." The Greek object means primarily "something," "anything" or "anyone."

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

ye -- The pronoun "you" is used explicitly as the subject of the sentence. Since it is already part of the verb, its use here creates emphasis on the "you" as we might say "you yourselves." It is plural.

missing "yourselves"  ---- (MW) The pronoun is used here explicitly as the subject of the sentence. Since this information is already in the verb, the sense is repetitive as we say "you yourselves."

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.
