2 Samuel 18:25-26

25So the man on the wall shouted a message to the king, to say what he had seen. The king said, ‘If the man is alone, he is bringing good news.’ The man who was running towards the city came much nearer.

26Then the man on the wall saw another man who was running towards the city. He called down to the guard at the city's gate, ‘Look! There is another man who is running alone!’ The king said, ‘He will bring good news, too.’
