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

worship - - (WT) "Worship" if from a verb that means "make obeisance," "fall down and worship," and specifically means to prostrate yourself before authority, as we would use the Chinese term, "kowtow."

what -- The word translated as "what" is a demonstrative pronoun ("this" "that"), but it often acts as a pronoun ("the one that), especially a connective pronoun ("the one that") introducing a dependent clause.

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

do -- (WT) This helping verb is used to create questions, commands, negative statements, and smooth word flow in English, but the Greek could be either a question or a statement. However, the tense of the verb is the past perfect, requiring a "have" 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.
