1 Samuel 23:20-23
20 Now, O king, come down whenever it pleases you to do so, and we will be responsible for handing him over to the king.”
21 Saul replied, “The Lord bless you for your concern for me.
22 Go and make further preparation. Find out where David usually goes and who has seen him there. They tell me he is very crafty.
23 Find out about all the hiding places he uses and come back to me with definite information. Then I will go with you; if he is in the area, I will track him down among all the clans of Judah.”
