Then -- "Then" is from the Greek word that means "at that time" and "then."

if -- (WW) The Greek word translated as "if" means "if might" indicates more of an expectation of something happening than "if" alone. In English, we say "when."

any man -- The word translated as "any man" means primarily "anything" or "anyone."

shall --  (CW) This helping verb "shall" does not indicate the future tense, but that the following verb describes a possibility, the subjunctive voice. A "might" or "should" in English is more appropriate, but is assumed in an "if/when/whoever/except" clause. Helping verbs are not needed in Greek since the main verb carries this information in its form. In English, the subjunctive is assumed in an "if/when/whoever" clause.

say -- "Say" is from means "to say" and "to speak" also. It has less a sense addressing and proclaiming.

unto -- This word "unto" comes from the dative case of the following word that requires the addition of a preposition in English, but the translator must decide which preposition to use: a "to" as an indirect object seem likely here.

you, -- The Greek pronoun "you" here is plural and in the form of an indirect object, "to you," "for you," etc. 

Lo, -- (CW)  "Lo" is from an adverb meaning "Lo! Behold!" and "See there!" In a humorous vein, this about how Christ uses this like we use the phrase "ta-da" in a magic show, or "see!" in French.

here -- The word translated as "here" means in manner, "in this way," referring to manner, or "here," referring to place.

is -- -- There is no verb "to be" here in the Greek. However, when a noun and pronouns appear in the form of a subject without a verb, the verb "to be" is assumed.

missing "the"  -- (MW) The untranslated word is the Greek definite article, which usually precedes a noun and, without a noun, takes the meaning of "the one." The Greek article is much closer to our demonstrative pronouns ("this," "that," "these," "those"). See this article for more. 

Christ, -- (UW) The word translated as "Christ" means "anointed." In the NT, it is understood to mean the Messiah, following the anointing of the kings of Israel. The Jews of Jesus's era thought they understood who the Messiah was and the source of his authority. He was a descendant of David, and his authority came from David as "the anointed" king of the Jews.

or -- "Or" is translated from a Greek word that means primarily "or" but serves as "than" in a comparison. The same word could also be the exclamation "hi" or the adverb meaning "in truth."

there; -- (WW) The word translated as "there" means in manner, "in this way," referring to manner, or "here," referring to place. It is the same as the "here" above.

believe -- (WF) The Greek word translated as "believe" does not apply to religious belief as much as it does trusting in other people, especially their word. Jesus usually uses it in contexts, as the one here, that apply to trusting words.  It is not in the form of a command. It is either the form of possibility ("you might") or the future tense ("you are going to.")

it -- There is no Greek pronoun here, but Greek does not need pronouns when the object can be assumed from the context. In English, they are added for the subject-verb-object form of our sentences.

not. -- The negative "not" used here is the Greek negative of a subjective opinion, commands, and requests. The sense is that "you don't want" to do something, not that it isn't done or don't think something that might be true. If it wasn't done or wasn't true, the objective negative of fact would be used. This is the negative used with commands and requests.
