David said to Abner, Art not thou, &c.— It may be asked, how could David make Abner and Saul hear, as it appears from the 13th verse that there was a great distance between them? The answer is easy. To ascend from one high hill to another, requires time; and in this sense, however adjacent, the two hills are remote. Time and pains are required to go from one to the other; but not so to make oneself heard.
