1 Samuel 26:1-4

The people of Ziph went to Saul at Gibeah and said to him, “David is hiding on the hill of Hakilah opposite Jeshimon.” So Saul went down to the Desert of Ziph with three thousand chosen men of Israel to look for David there. Saul made his camp beside the road on the hill of Hakilah opposite Jeshimon, but David stayed in the desert. When he heard Saul had followed him, he sent out spies and learned for certain that Saul had come to Hakilah.
