2 Samuel 1:1-3

1 Now it happened after the death of Saul, when David had returned from the slaughter of the Amalekites, that he stayed two days in Ziklag.

2 On the third day a man came [unexpectedly] from Saul's camp with his clothes torn and dust on his head [as in mourning]. When he came to David, he bowed to the ground and lay himself face down [in an act of great respect and submission].

3 Then David asked him, "Where do you come from?" He said, "I have escaped from the camp of Israel."
