1 Samuel 23:23-25

23Find 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.” 24So they set out and went to Ziph ahead of Saul. Now David and his men were in the Desert of Maon, in the Arabah south of Jeshimon. 25Saul and his men began the search, and when David was told about it, he went down to the rock and stayed in the Desert of Maon. When Saul heard this, he went into the Desert of Maon in pursuit of David.
