1 Samuel 23:22
Go, I pray you, prepare yet, and know and see his place where his haunt is, and who hath seen him there: for it is told me that he dealeth very subtilly. Go, I pray you, prepare yet, and know and see his place where his haunt is, and who hath seen him there: for it is told me that he dealeth very subtilly.
The Ziphites had already told Saul where David was hiding and had offered to guide Saul to him. In response Saul told them to prepare further by learning and seeing David's hiding place and finding out who had seen him there, because he had been told that David acted very cunningly. David learned of their intentions and moved away to the mountains between Maon and the Dead Sea.
