1 Samuel 23:20-23

Now come down, O king, according to all your heart’s desire to come down, and our part shall be to surrender him into the king’s hand.” And Saul said, “May you be blessed by the LORD, for you have had compassion on me. Go, make yet more sure. Know and see the place where his foot is, and who has seen him there, for it is told me that he is very cunning. See therefore and take note of all the lurking places where he hides, and come back to me with sure information. Then I will go with you. And if he is in the land, I will search him out among all the thousands of Judah.”
