Five years after the death of Shaul, they made Ish-Boshet king over Israel, and he reigned for two years. And Israel was for five years without a king, and half a year after the death of Ish-Boshet they made David king over Israel [(Rashi, Sanhedrin 55, 2). But the Tosafot wrote that half a year after the death of Shaul they made Ish-Boshet king, and after his death they were five years without a king until David became king, and so it is concluded].
