Saph saf (caph; Codex Vaticanus Saph; Codex Alexandrinus Sephe): A Philistine, one of the four champions of the race of Rapha ("giant") who was slain by Sibbecai, one of David's heroes (2 Samuel 21:18, 1 Chronicles 20:4). It is supposed by some that he was the son of the giant Goliath, but this is not proved. In 1 Chronicles 20:4, the same person is called "Sippai."
