The two Books of Chronicles (Hebrew: דברי הימים Diḇrê Hayyāmîm, "The Matters of the Days"; Greek: Παραλειπομένων, Paraleipoménōn) are the final books of the Hebrew Bible in the order followed by modern Judaism; in that generally followed in Christianity, they follow the two Books of Kings and precede Ezra–Nehemiah, thus concluding the history-oriented books of the Old Testament. In the Christian Bible, the books are commonly referred to as 1 Chronicles and 2 Chronicles, or First Chronicles and Second Chronicles.
The English title comes from the 5th century scholar Jerome, who referred to the book as a chronikon; in Hebrew it is called Divrei Hayyamim "The Matters [of] the Days", and in Greek, Paralipoménōn (Παραλειπομένων), "things left on one side".
Chronicles begins at the beginning of the history of humanity, with Adam, and the story is then carried forward, almost entirely by genealogical lists, down to the founding of the Israelite monarchy (1 Chronicles 1–9). The bulk of the remainder of 1 Chronicles, after a brief account of Saul, is concerned with the reign of David (1 Chronicles 11–29). The next long section concerns David's son Solomon (2 Chronicles 1–9), and the final part is concerned with the kingdom of Judah with occasional references to the kingdom of Israel (2 Chronicles 10–36). In the last chapter Judah is destroyed and the people taken into exile in Babylon, and in the final verses the Persian king Cyrus conquers Babylon, and authorises the restoration of the Temple in Jerusalem, and the return of the exiles.
A 3char is a domain name or AOL Instant Messenger (AIM) screen name with only three characters.
Since AIM screen name must start with a letter, there are only 33,696 valid three-character screen names (), and 46,656 valid three-character second-level domain names per top-level domain (
).
Since all of these screen names were registered in the middle 1990s, mostly by America Online members, these are a form of online "rarity", sought after by youths, hackers, or anyone wanting their screen name to appear impressive. 3chars are regularly sold or traded online. Many people have cracked the password of 3char accounts through brute-force search or using AOL Exploits and hacks to obtain the accounts.
Additionally, complex methods of screen name theft have been developed over time to allow AOL crackers to gain unauthorized access to rare screen names, including 3chars. In late 2000, one AOL cracker reportedly developed software which used an AOL security glitch to gain access to all three-character screen names vulnerable to that security issue, effectively bringing many thousands of these screen names under his control. This resulted in numerous long-time users losing their accounts, and began a cottage industry of screen name barter and sale.
