According to the Bible, Daniel, also known as Chiliab, was the second son of David, King of Israel, with Abigail, widow of Nabal the Carmelite, David's third wife. ( , cf ) Unlike the other of David's three elder sons, Amnon, Absalom, and Adonijah who were important characters in 2 Samuel, Daniel is only named in the list of David's sons and no further mention is made to him. Though being the second son, Daniel was not a contender for the throne of Israel, even after the death of the first-born Amnon, the third-born Absalom and fourth-born Adonijah. The throne eventually passed to his younger half brother, Solomon.
Daniel is known as Daluyah in the Septuagint.
According to Rashi, some questioned whether Abigail was pregnant through David or her first husband, Nabal; therefore, God arranged that Daniel would resemble David. It is possible his name "Chiliab," which can be translated "perfection of the father," is a reference to (or cause of) that legend.sw:Kileabuyi:דניאל (בן דוד)
