פירוש על שמואל ב 1:2

Behold a man came from the camp. The Pesikta¹Pesikta Rabosi 12,9. brings an opinion that this man is Doeig,²Doeig HaEdomi is first mentioned in Shmuel 1,21:8. but the explanation is indefensible in my heart.³It is clear from Shmuel 1, 22:18 that Shaul knew Doeig. Therefore, if in fact this man is Doeig, why did Shaul have to ask later in v. 8, “Who are you?” (Seder Hadoros, p. 102).
