1 Samuel 23:22-23

22Please go and find out for sure, and see the place where his hideout is, and who has seen him there. For I am told he is very crafty.

23See therefore, and take knowledge of all the lurking places where he hides; and come back to me with certainty, and I will go with you. And it shall be, if he is in the land, that I will search for him throughout all the clans of Judah.”
