1 Samuel 23:22-23

22Go now, make more sure, investigate and scout out his place where he usually goes and who has seen him there. For I have been told that he is very cunning.

23Look around and see in which of all the hiding places he has been hiding, and return to me with certainty, and I will go with you. If he is in the area, I will search him out among all the clans of Judah.”
