2 Samuel 18:21 In-Context

19 Then Ahimaaz son of Zadok said, "Let me run, and carry tidings to the king that the Lord has delivered him from the power of his enemies."
20 Joab said to him, "You are not to carry tidings today; you may carry tidings another day, but today you shall not do so, because the king's son is dead."
21 Then Joab said to a Cushite, "Go, tell the king what you have seen." The Cushite bowed before Joab, and ran.
22 Then Ahimaaz son of Zadok said again to Joab, "Come what may, let me also run after the Cushite." And Joab said, "Why will you run, my son, seeing that you have no reward for the tidings?"
23 "Come what may," he said, "I will run." So he said to him, "Run." Then Ahimaaz ran by the way of the Plain, and outran the Cushite.
