David, or Dawit as he is often referred to in the novel, is a man who has been alive since the 1500's. He was part of a group of 59 men who accepted an offer made by Khaldun to have immortality. David questions Khaldun directly about how he inherited immortality on one of their first meetings. Even after he learns that the miracle of Khaldun's immortality came from the theft of Christ's blood, Dawit still agrees to undergo the ritual. Because Khaldun knew nothing of Christ and did not profess to be a Christian, Dawit also has no interest in seeking God or Christ. He tells Jessica that he is an atheist soon after they begin dating. Although Jessica has hopes of being able to convert her husband, she has not yet been successful in their years of marriage.
