{{quote|Some of you may be wondering - "What's up with this unhealthy obsession with the number 7?"  This page offers some insights.|[[Luke Smith]], linking to this very page<ref>http://www.bungie.net/News/content.aspx?cid=14650</ref>}}

{{quote|Cause that's the best number. It's like rock. Nothing beats rock or 7.|[[Michael Wu]]}}

[[Bungie Studios]] has long enjoyed using the number '''Seven (7)''' in its games in many prominent ways<ref>[http://marathon.bungie.org/story/seven.html Marathon.Bungie.Org: The Number Seven]</ref>. [[Ensemble Studios]] and authors also have certain obvious seven references in their works about ''Halo''. While almost anything can be made into a reference to something with effort or construed accidentally through [[wikipedia:pareidolia|pareidolia]], the following attempts to list the intentional references Bungie placed into ''Halo'' for the fans to find. As such, not all of these references may be fully accurate, and many of them may be proven to be false at any time. Bungie's obsession with with the number seven may be attributed to (or be a determining factor) why [[John-117]] is considered lucky, as 7 is considered a lucky number.

}}

==117==
'''117''' is [[Master Chief]]'s [[SPARTAN]] tag number, but there is more than meets the eye when it comes to this number, including many religious and historical references.

*1x1x7=7

*[[Yayap]] determines that the Master Chief will need to flee the ''Pillar of Autumn'' via hatch E-117. Likely a reference to his Spartan number.<ref>[[Halo: The Flood]], Page 333</ref>

*[[Dr Halsey]] points out that there is only one hour and 17 minutes (1:17) left before the portal closes.<ref>[[Halo:Ghosts of Onyx]], page 311</ref>

*Both the trailers for Halo 3: ODST and Halo: Reach are 1:17. This may alternatively be a reference to 7, as 1:17 in seconds is 77.

===Biblical Reference===
{{Scroll box
|content = *[[John-117]] is believed by many fans to be a reference to [[Wikipedia:New Testament|New Testament]] of the Christian Bible.

*In the year 117, the 7th Pope of the Catholic Church was named, Sixtus I, as well as John 1 becoming 7th bishop of Jerusalem.

*The Gospel of John speaks of the 7 miracles of Jesus, the last one, John claims, culminating in his death and resurrection.

*[[Bungie Studios]] is known to have placed many biblical references in their earlier [[Marathon]] video game series, and many other such references have been found in the Halo series.

*Here are passages from the [[Wikipedia:Book of Revelation|Book of Revelation]] (more formally known as The Revelation of St. John the Divine). Revelation in Greek is called "The Apocalypse", a title possibly shortened from "The Apocalypse of John."

:"And when I saw him, I fell at his feet as dead. And he laid his right hand upon me, saying unto me, Fear not; I am the first and the last: I am he that liveth, and was dead; and, behold, I am alive for evermore, Amen; and have the keys of hell and of death."
:''Book of Revelation, KJV. Chapter 1 - verses 17 and 18.''


:"And when they shall have finished their testimony, the beast that ascended out of the pit shall make war against them, and shall overcome them, and kill them."
:''Revelation. 11:7''

*And here are passages from the Gospel of John. These are thought less likely to be references:

:"Then after that saith he to his disciples, Let us go into Judea again."
:''Gospel of John, 11:7''
:"For the law was given by Moses, [but] grace and truth came by Jesus Christ."
:''Gospel of John, 1:17''
:"There came a man who was sent from God; his name was John. He came as a witness to testify concerning that light, so that through him all men might [http://www.youtube.com/watch?v=3rridXskgWg believe]."
:''Gospel of John, 1:1-7''
:(Out of all of these, perhaps the most likely to be a reference to Spartan-117 would be the last verse.)


*Leviticus 25:9 (Sierra 259 in the Halo Reach trailer) is a conversation between Moses and God about the year of jubilee, and the past ''Harvest''(!?!):

*Leviticus 25:8
"Count off '''seven''' Sabbaths of years—'''seven''' times '''seven''' years—so that the '''seven''' Sabbaths of years amount to a period of forty-nine years."

*Leviticus 25:9
"Then have the trumpet sounded everywhere on the tenth day of the '''seventh''' month; on the Day of Atonement sound the trumpet throughout your land."


*Halo 3's plot also resembles the story of Noah's Ark. Because the Forerunners kept a few of every sentient species in the galaxy in the [[Ark]] because the parasitic life-forms known as the Flood were coming, much like in the bible story of Noah's Ark. The flood was coming and Noah put two of every animal in the Ark to save them from the water flood, much like the Forerunners did before they activated the Halos to keep the other lesser sentient species from extinction.
}}

===Site 117===

Alternatively, others believe the number to be a reference to "Site 117", an archaeological site containing the first evidence of a human battle. The site is near Jebel Sahaba, Nubia and dates from between 12,000-10,000 BC. The site contains 59 human remains of men, women and children who were clearly killed with primitive hunting implements.

===117 and 7===

It is conjectured that the numbering system for Halo installations' Monitors is, where <math>n</math> is the number of their installation, <math>7^{n-1}</math>. With this in mind, it is reasonable to assume that the number of the Monitor of Installation 07 is <math>7^6=117649</math>. As well as including the number 117 when it is written in base-10 (decimal), it also includes 649. <math>9+4-6=7</math>.

The number 819 appears numerous times in the Marathon series. <math>819/7=117</math>. This tradition started in ''[[Marathon (video game series)|Marathon Infinity]]'', with two secret terminals on the first and last levels of campaign mode. At first sight, these terminals seemed to contain nonsense. However, if the data from both terminals was copied into ResEdit (the classic [[wikipedia:History of Mac OS|Mac OS]]'s hexadecimal editor), converted into text format, then expanded twice with [[wikipedia:Stuffit Expander|Stuffit Expander]], a map file would be revealed which could then be loaded in ''Infinity''. The 819 was a reference to Hamish Sinclair, a prominent member of the community at marathon.bungie.org (the sister site of [[halo.bungie.org]]) as if one assigned letters to numbers sequentially (<math>a = 1, b = 2, c = 3\ldots</math>) then Sinclair's initials, H.S., would be 8.19.<ref>http://marathon.bungie.org/story/hangar96.html</ref>

===''Marathon''===

* The music for ''Marathon 2: Durandal'' and ''Marathon Infinity'' was composed and produced by an external music group called 'Power of Seven'. (Similarly, ''Marathon 2: Durandal'' also has an achievement with the same name.)

* In the original ''[[Marathon]]'', the barrels all have a backwards 7 in the serial number.

===117 Trivia===

*In ''Halo 3'', the game won't let you input the I.D. tag "I (upper-case i)-17", "l (lower-case L)-17", or "T-17" saying that these numbers are already reserved by the ''[[UNSC]]''.

*In [[Halo: The Flood]], [[Yayap]] tells 'Zamamee that Master Chief must go through corridor E-'''117'''.
*The Halo: Reach Video Game Awards Trailer takes 117 MB of memory to download from the Xbox Live Marketplace.
*It is likely that one reason Bungie chose 7 as their "number of obsession" is because 7 is often seen as a lucky number which coincides with the idea that Master Chief's (John's) defining trait is that he is lucky.
*117 is the hotline for the [[wikipedia:Philippine National Police|PNP]], another one of the "hidden" references to the Philippines, notable for being a westernized Southeast-Asian country.

+The number 819 appears numerous times in the Marathon series. <math>819/7=117</math>. This tradition started in ''[[Marathon (video game series)|Marathon Infinity]]'', with two secret terminals on the first and last levels of campaign mode.

However, if the data from both terminals was copied into ResEdit (the classic [[wikipedia:History of Mac OS|Mac OS]]'s hexadecimal editor), converted into text format, then expanded twice with [[wikipedia:Stuffit Expander|Stuffit Expander]], a map file would be revealed which could then be loaded in ''Infinity''. The 819 was a reference to Hamish Sinclair, a prominent member of the community at marathon.bungie.org (the sister site of [[halo.bungie.org]]) as if one assigned letters to numbers sequentially (<math>a = 1, b = 2, c = 3\ldots</math>) then Sinclair's initials, H.S., would be 8.19.<ref>http://marathon.bungie.org/story/hangar96.html</ref>
