1 Samuel 26:13,14

And stood on the top of a hill On such a rock or precipice that there was no coming to him but by taking a circuit round. So that it might be said, in respect of the way whereby only they could come to him, that he stood afar off, and that there was a great distance between them; and yet, though his person might thus be out of their reach, his voice might be distinctly heard, which in a clear air, and in the silence of the night, it might be at a considerable distance. David cried to the people It is probable this was early in the morning.
