KJV — word by word

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 can be translated as "not only...but also". After words implying sameness "as".

for -- "For...sakes" is a preposition that means "over", "beyond", "concerning", "on behalf of" and "instead of", with many other specific uses.

their -- The word translated as "their" is the Greek adjective that acts like our third-person pronoun. The form is the third person, plural in the genitive form. It is used as a possessive or the object of a verb or preposition. As a preposition's object means a movement away from something or a position away from something else.

sakes - This completes the idea of the preposition.

I -- This is from the  pronoun "I" being used here. When it has no verb, the verb "is" or the previous verb is assumed. When the subject of the sentence 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 subject pronoun repeats the information in the verb so it should be repeated in English like "I myself".

sanctify -- This word is perhaps, an unusual form of a Greek verb meaning "to dedicate to God" and "to sanctify" usually by burning an offering. It may also be a verb form of a Greek noun, meaning "a thing that creates awe". In a good sense, this can mean holy or sacred, but it also means accursed. Another way to think about this word is that it describes something set apart only for God.

myself, -- The Greek reflexive pronoun is translated as "myself". It is used primarily as the object of a preposition. As a genitive object means a movement away from something or a position away from something else.

that -- The word translated as "that" is a conjunction that starts a subordinate clause "that", "when", "in order that", "when" or "because." It is used as an introduction to a command, where it isn't translated.

they -- This is from the third-person, plural form of the verb.

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

might -- This helping verb "might" indicates that the verb indicates a possibility, the subjunctive. Helping or auxiliary verbs are needed to translate the Greek verb forms into English.

be -- (CW) The verb "be" 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" where it doesn't connect to characteristics or conditions. This is not used to create a passive since the endings of Greek verbs determine the voice. Translating it as "exist" is less confusing.

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

sanctified -- (WT, WV)  The "sanctified" here means to "purify" for dedication to the Divine, "to dedicate to God" and "to sanctify", usually by burning an offering. The noun form means "a thing that creates awe". Another way to think about this word is that it describes something set apart only for God. It is a participle, in the past perfect tense, in a passive form so "having been purified".

through -- (CW) The word translated as "through" means "in", "within", "with" (an instrument), "by" (near), "by" (means of), "during" (time) or "among" with a dative object as the one here. When referring to time, it means "during". It can mean "on", "at" or "by", in the sense of "near". This is not the word usually translated as "through".

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". 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.
