2 Samuel 18:25

Then Ahimaaz the son of Zadok said yet again to Joab, “But come what may, please let me also run after the Cushite.”

Joab said, “Why do you want to run, my son, since you will have no reward for the news?”

“But come what may,” he said, “I will run.”

He said to him, “Run!” Then Ahimaaz ran by the way of the Plain, and outran the Cushite.

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.

The watchman saw another man running; and the watchman called to the gatekeeper and said, “Behold, a man running alone!”

The king said, “He also brings news.”

The watchman said, “I think the running of the first one is like the running of Ahimaaz the son of Zadok.”

The king said, “He is a good man, and comes with good news.”

Ahimaaz called, and said to the king, “All is well.” He bowed himself before the king with his face to the earth, and said, “Blessed is the LORD your God, who has delivered up the men who lifted up their hand against my lord the king!”
