2 Samuel 18:19-23

19Zadok's son Ahimaaz said to Joab, ‘Let me run to give the king the good news. I will tell him that the Lord has saved him from the power of his enemies.’

20Joab said, ‘No, it will not be good news for the king. His son is dead. You must not take this news today. Another day there will be good news for you to take to him, but not today.’

21Then Joab spoke to a servant who came from Ethiopia, ‘Go now to the king. Tell him what you have seen.’ The man bent down in front of Joab and then he ran off with the message.

22Zadok's son Ahimaaz spoke to Joab again. He said, ‘I am not afraid of what may happen to me. Please let me run after the Ethiopian man.’ But Joab replied, ‘Why do you want to go as well? The king will not give you any gift for this news.’

23Ahimaaz said, ‘But I do want to go, whatever happens.’ So Joab said, ‘Run after him, then!’ So Ahimaaz ran fast along a road in the Jordan Valley. He arrived near Mahanaim before the Ethiopian man.
