In the Bible, 666 is the number of Adonikam's descendants who return to Jerusalem and Judah from the Babylonian exile (see Ezra 2:13).In the Bible, 666 is the number of talents of gold Solomon collected each year (see 1 Kings 10:14 and 2 Chronicles 9:13).The Number of the Beast is cited as 616 in some early biblical manuscripts, the earliest known instance being in Papyrus 115. This is known as hexakosioihexekontahexaphobia. Some people take the Satanic associations of 666 so seriously that they actively avoid things related to 666 or the digits 6-6-6. It is common to see the symbolic role of the integer 666 transferred to the numerical digit sequence 6-6-6.

Such popular references are therefore too numerous to list. References in contemporary Western art or literature are, more likely than not, intentional references to the Beast symbolism.

Earnest references to the number occur both among apocalypticist Christian groups and in explicitly anti-Christian subcultures. In modern popular culture, 666 has become one of the most widely recognized symbols for the Antichrist or, alternatively, the devil. Some manuscripts of the original Koine Greek use the symbols χξϛ chi xi stigma (or χξϝ with a digamma), while other manuscripts spell out the number in words. In the Textus Receptus manuscripts of the New Testament, the Book of Revelation ( 13:17–18) cryptically asserts 666 to be "the man's number" or "the number of a man" (depending on how the text is translated) associated with the Beast, an antagonistic creature that appears briefly about two-thirds into the apocalyptic vision. The Roman numeral for 666, DCLXVI, has exactly one occurrence of all symbols whose value is less than 1000 in decreasing order (D = 500, C = 100, L = 50, X = 10, V = 5, I = 1). 666 is the sum of the first 36 natural numbers ( ∑ i = 1 36 i + 666 is 666.
