All -- The word translated as "all" is the Greek adjective meaning "all," "the whole," "every," and similar ideas. When it is used as a noun, we would say "everything." As an adverb, it means "in every way," "on every side," and "altogether."

who -- (CW) The word translated as "who" means "as great as," "as much as," and similar ideas of comparison.

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.

come -- The word translated as "come" primarily means "to start out" but Christ usually uses it to mean "come" but not always. It indicates movement, especially its beginning, without indicating a direction toward or away from anything, so it works either as "start," "come," or "go," but it is more like our phrase "being underway." Our English word "show up" captures both the "start" and "come" ideas. See this article for more.

before -- The Greek preposition translated as "before" means (of place) "before," "in front of," (of time) "before," (of preference), "rather than," "more than," and so on.

me -- "Me" is the first-person possessive singular pronoun.   As a genitive object of a preposition, as here, it means a movement away from something or a position away from something else.

are -- The verb "are" 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.

thieves - "Thieves" is from the Greek noun that means "thief," "cheat," and "knave."

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."

robbers, -- The Greek  noun translated as "robbers" means "robber" or "pirate."

but -- (CW) 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."

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. 

sheep -- "Sheep" is Christ's symbol for his followers. The Greek word refers to any domesticated animal and works better if translated simply as "flock" or "herd." The flock follows the shepherd, which is above them. It is also together, a united group.

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.

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.

listened - -- "Listened " is from a Greek verb that means "to hear" and "to listen." It has the same sense as the English not only of listening but of understanding.  It is the most common verb that Christ uses meaning "to hear." It also means "to listen" and "to understand," but amusingly, it also means "to be silent."

to -- This word "to"  comes from the genitive case of the following word that requires the addition of a preposition in English.  The most common is the "of" of possession. However, with this verb, the genitive object is the one heard from.

them.-- The word translated as "them" is the Greek word commonly translated as third-person pronouns in English.
