2 Samuel 18:23 WEB

²¹  Then said Joab to the Cushite, Go, tell the king what you have seen. The Cushite bowed himself to Joab, and ran.

²²  Then said Ahimaaz the son of Zadok yet again to Joab, But come what may, Please let me also run after the Cushite. Joab said, Why will you run, my son, seeing that you will have no reward for the news?

²³  But come what may, [said he], I will run. He said to him, Run. Then Ahimaaz ran by the way of the Plain, and outran the Cushite.

²⁴  Now David was sitting between the two gates: and the watchman went up to the roof of the gate to the wall, and lifted up his eyes, and looked, and, behold, a man running alone.

²⁵  The watchman cried, and told the king. The king said, If he be alone, there is news in his mouth. He came apace, and drew near.
