Do  -- (WF) This helping verb is added to make this a negative command, but the Greek is a statement about what could or should happen.

not -- The negative 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. If it wasn't done, the objective negative of fact would be used.

suppose -- The word translated as "suppose" means "to be used by custom" and "to be accustomed to." It is the verb form of the Greek word translated as "law," which actually means "traditions," "norms," or "customary behavior."  It is a normal active verb a form indicating a possibility or something happening in the future. "You might be getting accustomed to" or "you are going to get accustomed to."

that -- The word translated as "that" introduces a statement of fact.

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

have -- (WT) This helping verb "have" indicates that the verb is the past tense. However, the form of the word is something that happens at some point in time, past, present, or future.

come -- The word translated as "I am come" primarily means "to start out." 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 "to underway" or "to show up." It is in a form that could mean "I have come" but it could also mean "they have come." The context doesn't really tell us which version is correct. It is easy to imagine this verse being asked about him or about the Romans.

to -- This "to" is added because the infinitive form of the verb requires a "to" in English.

bring -- (WW) The word translated as "to bring" has a number of meanings revolving around "throw" as we do in English with both "throw" and "toss." Christ more frequently uses this word in the sense of to "cast out" or "throw out" with a different preposition, "out" instead of "upon." Though it can also mean "pour" or "let fall," which does work with "upon." It is not any of the words that Christ uses frequently that are translated as "send" or "put." This word is usually translated as "cast" in the NT and "toss" in the translations here. Christ uses it dozens of times in the Gospels and it always has the sense of tossing something, most commonly, for "casting out" demons. The one exception is when it is translated as "put" in John 18:11 where Christ tells Peter to "toss" or "let fall" his sword into his scabbard. This idea of throwing something through the air is also captured by the English words "launch" which also has the sense of "initiate" which is also a sense of this word.

peace  -- "Peace" is the Greek term that means "harmony between individuals and nations" and the general idea of safety, security, and prosperity. It is the opposite of the state of war. In Hebrew, the word for peace was used in salutations and as an inquiry as to one's health.

to -- (WW) The word translated as "on" means "on (a place)" with certain forms of nouns,  the noun's form here is that of an object, which eliminates its use as a place, but it can mean an extension "over (a space)" or a cause "for" this purpose. So, "over the earth" or "for the earth."

the  -- This 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. 

earth: The word translated as "earth" means the physical planet, ground, or land.

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

did -- (WT) This helping verb "did" indicates that the verb is the past tense. However, the form of the word is something that happens at some point in time, past, present, or future.

not  -- Another Greek word is translated as the second "not" is the Greek negative used to deny objective facts, not opinions. It makes a negative statement of fact. Adding "really" often captures its specific meaning in the context.

come -- The word translated as "come" is the same as word in the same form as the "I come" above. It  primarily means "to start out." 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 "to underway" or "to show up." Since the form could mean the past, present, or future, the clause "I show up/they show up" is more accurate in terms of tense. The context doesn't really tell us which way version is correct. Given the idea of "Pax Romana" it is easy to think about this word being applied to the Romans.

to -- This "to" is added because the infinitive form of the verb requires a "to" in English.

bring-- (WW)  The word translated as "to bring" has a number of meanings revolving around "throw" as we do in English with both "throw" and "toss." Christ more frequently uses this word in the sense of to "cast out" or "throw out" with a different preposition, "out" instead of "upon." Though it can also mean "pour" or "let fall," which works with the "upon." It is not any of the words that Jesus uses frequently that are translated as "send" or "put." This word is usually translated as "cast" in the NT as in  "casting out" demons. However, this word is somewhat light-hearted in the sense of "toss." In John 18:11, Jesus uses this word to tell Peter to "toss" or "let fall" his sword into his scabbard. This idea of throwing something through the air is also captured by the English words "launch" which also has the sense of "initiate" which is also a sense of this word.

peace  -- "Peace" is the Greek term that means "harmony between individuals and nations" and the general idea of safety, security, and prosperity. It is the opposite of the state of war. In Hebrew, the word for peace was used in salutations and as an inquiry as to one's health.

but -- The Greek word translated as "but" denote an exception or simple opposition. "Still" or "rather" work well when the word isn't being used as a conjunction.

a -- There is no indefinite article in Greek, but when a word doesn't have a definite article, the indefinite article can be added in English translation.

sword. -- The term for "sword" means a short sword, a weapon much more like a machete since the Greek is the source for the English word. It is specifically the type of weapon used for making sacrifices, by assassins, bodyguards, and jugglers. Jugglers is particularly interesting because of the word "toss." This is exactly the type of sword you toss around when juggling.
