According to the Book of Genesis, Dan (Hebrew: דָּן, Standard Dan Tiberian Dān; "judgement" or "he judged") was the fifth^{[citation needed]} son of Jacob with Bilhah. He was Bilhah's first son. He was the founder of the Israelite Tribe of Dan. In the biblical account, Dan's mother is described as Rachel's handmaid, who becomes one of Jacob's wives. (Genesis 30:4,6)

The text of the Torah explains that the name of Dan derives from dananni, meaning he has judged me, in reference to Rachel's belief that she had gained a child as the result of a judgment from God.

Owing to the Book of Judges, in the account of Micah's Idol, describing the tribe of Dan as having used ephod and teraphim in worship, and Samson (a member of the tribe of Dan) being described as failing to adhere to the rules of a Nazarite, classical rabbinical writers concluded that Dan was very much a black sheep; in the Book of Jeremiah, the north of Canaan is associated with darkness and evil, and so rabbinical sources treated Dan as the archetype of wickedness. In the apocryphal Testaments of the Patriarchs, Dan is portrayed as having hated Joseph, and having been the one that invented the idea of deceiving Jacob by the smearing of Joseph's coat with the blood of a kid; in the apocryphal Prayer of Asenath, Dan is portrayed as plotting with the Egyptian crown prince, against Joseph and Asenath. In the Blessing of Jacob, Dan is described as a serpent, which seems to have been interpreted as connecting Dan to Belial, a connection made, for example, in the apocryphal Testament of Dan; early Christian writers, such as Irenaeus and Hippolytus, even believed that the Antichrist would come from the tribe of Dan drawing the belief from a verse from the Book of Jeremiah which states the snorting of [the enemy's] horses was heard from Dan.

Dan is a name. It refers sometimes to the short form of the name Daniel. Dan, or the acronym DAN may refer to the following:

The Bible (from Koine Greek τὰ βιβλία ta biblia "the books") is any one of the collections of the primary religious texts of Judaism and Christianity. There is no common version of the Bible, as the contents and the order of the individual books (Biblical canon) vary among denominations. The 24 texts of the Hebrew Bible are divided into 39 books in Christian Old Testaments, and complete Christian Bibles range from the 66 books of the Protestant canon to the 81 books of the Ethiopian Orthodox Church Bible. The Hebrew and Christian Bibles are also important to other Abrahamic religions, including Islam and the Bahá'í Faith, but those religions do not regard them as central religious texts.

The Hebrew Bible, or Tanakh, is divided into three parts: (1) the five books of the Torah ("teaching" or "law"), comprising the origins of the Israelite nation, its laws and its covenant with the God of Israel; (2) the Nevi'im ("prophets"), containing the historic account of ancient Israel and Judah focusing on conflicts between the Israelites and other nations, and conflicts among Israelites – specifically, struggles between believers in "the LORD God" and believers in foreign gods, and the criticism of unethical and unjust behavior of Israelite elites and rulers; and (3) the Ketuvim ("writings"): poetic and philosophical works such as the Psalms and the Book of Job.

Daniel Keenan "Dan" Savage (born October 7, 1964) is an American author, media pundit, journalist and newspaper editor. Savage writes the internationally syndicated relationship and sex advice column Savage Love. Its tone is frank in its discussion of sexuality, often humorous, and hostile to social conservatives and Rick Santorum's views on homosexuality. Savage has clashed with cultural conservatives on the right, and the gay establishment, on the left. He has also worked as a theater director, both under his real name and under the name Keenan Hollahan, using his middle name and his grandmother's maiden name. In 2010, Savage and his husband Terry Miller began the It Gets Better Project to help prevent suicide among LGBT youth.

Dan Savage was born to William and Judy Savage in Chicago, Illinois. He is of Irish ancestry. The third of four children, Savage was raised as a Roman Catholic and attended Quigley Preparatory Seminary North, which he has described as "a Catholic high school in Chicago for boys thinking of becoming priests." Though Savage has stated that he is now "a wishy-washy agnostic" and an atheist, he has said that he still considers himself "culturally Catholic."
