1 Samuel 23:25-26

25and Saul and his men went to seek him. When David was told about it, he went down to the rock and stayed in the Wilderness of Maon. And when Saul heard of this, he pursued David there.

26Saul was proceeding along one side of the mountain, and David and his men along the other side. Even though David was hurrying to get away, Saul and his men were closing in on David and his men to capture them.
