Bible Verses About Watchmen: Reported the approach of all strangers

Now David was sitting between the two gates when the watchman went up to the roof of the gateway by the wall, looked out, and saw a man running alone.

So he called out and told the king. “If he is alone,” the king replied, “he bears good news.” As the first runner drew near,

the watchman saw another man running, and he called out to the gatekeeper, “Look! Another man is running alone!” “This one also brings good news,” said the king.

The watchman said, “The first man appears to me to be running like Ahimaaz son of Zadok.” “This is a good man,” said the king. “He comes with good news.”

So a horseman rode off to meet Jehu and said, “This is what the king asks: ‘Have you come in peace?’” “What do you know about peace?” Jehu replied. “Fall in behind me.” And the watchman reported, “The messenger reached them, but he is not coming back.”

So the king sent out a second horseman, who went to them and said, “This is what the king asks: ‘Have you come in peace?’” “What do you know about peace?” Jehu replied. “Fall in behind me.”

Again the watchman reported, “He reached them, but he is not coming back. And the charioteer is driving like Jehu son of Nimshi—he is driving like a madman!”

For this is what the Lord says to me: “Go, post a lookout and have him report what he sees.

When he sees chariots with teams of horsemen, riders on donkeys, riders on camels, he must be alert, fully alert.”

Look, here come the riders, horsemen in pairs.” And one answered, saying: “Fallen, fallen is Babylon! All the images of her gods lie shattered on the ground!”
