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

I -- This is from the first-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.

given -- The verb translated as "given" means "to give," "to grant," "to hand over," "appoint," "establish," and "to describe." It is almost always translated as some form of "give."

unto -- 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

them -- The word translated as "them" is the Greek word commonly translated as third-person pronouns in English. It is a plural indirect object.

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.  

words -- (CW) The Greek word translated as "words" is not the common word meaning "idea" that is mistranslated as "words" in the Bible. Nor is it the Greek word for "words." It is another word that specifically means "what is spoken." This is the root word for the English word "remarks" and "remarks" that captures this concept well.

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

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

gavest -- The verb translated as "gave" means "to give," "to grant," "to hand over," "appoint," "establish," and "to describe." It is almost always translated as some form of "give."

me -- The "me" is in the indirect object form of the first-person pronoun, so usually "to me,""for me," and "by me."

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."

they - The word translated as "they" is the Greek word commonly translated as third-person pronouns in English. It is a plural subject. It is used because the following verb could be either the third-person or the first person.

have -- (WT) This helping verb "have" indicates that the verb is the tense indicating an action completed in the past. This is not the tense of the verb here.

received .-- The word translated as "received" primarily means "take." However, it means "receive" in the same sense that we use "get" to mean "receive" and has many different uses as we use "get" in English. Among these are the ideas of "understanding" and "possessing." The form could either means "they get" or "I get," but the pronoun before clarifies it.

them, -- This English objective pronoun is added and not in the Greek source.   In Greek, pronoun objects are not repeated after each verb because they are implied by their first occurrence.

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."

have -- (WT) This helping verb "have" indicates that the verb is the tense indicating an action completed in the past. This is not the tense of the verb here.

known -- "Known" is a verb that means "to know," "to recognize," "make known," "to know carnally," and "to learn." The idea of "realize" seems to capture most senses of this word better than "know," which is the meaning of "have seen."

surely --"Surely" is an adverb that means "actually," "really," "truly," and "obviously." It is from the adjective meaning "unconcealed" that is usually translated as "true." It is not commonly used by Jesus in Matthew and Mark. Luke used it to replace the Aramaic word amen ("truly"). "Truly" works best because the root of this word is the same as "truth."

that --  (CW) The word translated as "that" introduces a statement of fact or cause, "for what," "because," "since," and "wherefore." It is translated as "for" at the beginning of the sentence. It is not the word usually translated as "that."

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

came out  --  (MM) The word translated as "came out " means literally "to go or come out," but it has a secondary meaning of "making something come true." In some verses, its sense is "started out" from the primary meaning of its root. The form could either mean "I came out" or "they came out."

from -- The Greek preposition translated as "of" has many meanings, many of which depend on the case of its object. With the genitive, the sense is motion, "from the side of," "from beside," and generally "from."

thee.  -- The word translated as "thee" is the genitive form of the singular, second-person pronoun, which is most commonly the possessive form. As a genitive object of a preposition, as here, it means movement away from something or a position away from something else.

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."

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

have -- (WT) This helping verb "have" indicates that the verb is the tense indicating an action completed in the past. This is not the tense of the verb here.

believed   -- (CW) The Greek word translated as "believe" does not apply to religious belief as much but trusting or relying upon other people, especially their words. Jesus usually uses it in contexts, such as the one here, that apply to trusting words.

that --  (CW) The word translated as "that" introduces a statement of fact or cause, "for what," "because," "since," and "wherefore." It is translated as "for" at the beginning  of the sentence.

thou -- The  "you" here in the second-person pronoun in form of a singular subject. Since, as the subject of the sentence, it is part of the verb, its explicit use repeats the idea of who is speaking, "you." Saying "you yourself" captures this feeling in English.

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

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

send -- (CW) The "send" here is a word that means "to send off" and "dispatch." It is the source of our word "apostle." It is not the simple word, "send."

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.
