1 Samuel 23:19-23

Then Ziphites came up to Saul at Gibeah, saying, “Is David not keeping himself hidden with us in the strongholds at Horesh, on the hill of Hachilah, which is south of Jeshimon?

Now then, O king, come down, since you fully desire to do so; and our part shall be to hand him over to the king.”

Saul said, “May you be blessed of the Lord, since you have had compassion on me.

Go now, be more persistent, and investigate and see his place where he is hiding, and who has seen him there; for I am told that he is very cunning.

So look, and learn about all the hiding places where he keeps himself hidden, and return to me with certainty, and I will go with you; and if he is in the land, I will search him out among all the thousands of Judah.”
