2 Samuel 18:23-24

23“Whatever may come of it, I want to run!” So he said to him, “Run!” Ahimaaz ran by the way of the plain, and so passed the Cushite.

24Now David was sitting between the two gates. When the watchman on the roof over the gate walked over to the wall, he lifted up his eyes and looked, and all of a sudden, he saw a man running alone.
