'Watchman' in the Bible
In the meantime Absalom fled. When the servant who was the watchman looked up, he saw many people coming from the west on a road beside the hill.
Now David was sitting between the inner and outer gates, and the watchman went up to the roof over the gate at the wall. When he looked, he saw a man running by himself.
So the watchman called out and informed the king. The king said, "If he is by himself, he brings good news." The runner came ever closer.
Then the watchman saw another man running. The watchman called out to the gatekeeper, "There is another man running by himself." The king said, "This one also is bringing good news."
The watchman said, "It appears to me that the first runner is Ahimaaz son of Zadok." The king said, "He is a good man, and he comes with good news."
Now the watchman was standing on the tower in Jezreel and saw Jehu's troops approaching. He said, "I see troops!" Jehoram ordered, "Send a rider out to meet them and have him ask, 'Is everything all right?'"
So the horseman went to meet him and said, "This is what the king says, 'Is everything all right?'" Jehu replied, "None of your business! Follow me." The watchman reported, "The messenger reached them, but hasn't started back."
The watchman reported, "He reached them, but hasn't started back. The one who drives the lead chariot drives like Jehu son of Nimshi; he drives recklessly."
The house he builds is as fragile as a moth's cocoon, like a hut that a watchman has made.
A song of ascents, by Solomon. If the Lord does not build a house, then those who build it work in vain. If the Lord does not guard a city, then the watchman stands guard in vain.
Here is a message about Dumah: Someone calls to me from Seir, "Watchman, what is left of the night? Watchman, what is left of the night?"
The watchman replies, "Morning is coming, but then night. If you want to ask, ask; come back again."
"Son of man, I have appointed you a watchman for the house of Israel. Whenever you hear a word from my mouth, you must give them a warning from me.
"Son of man, speak to your people, and say to them, 'Suppose I bring a sword against the land, and the people of the land take one man from their borders and make him their watchman.
But suppose the watchman sees the sword coming and does not blow the trumpet to warn the people. Then the sword comes and takes one of their lives. He is swept away for his iniquity, but I will hold the watchman accountable for that person's death.'
"As for you, son of man, I have made you a watchman for the house of Israel. Whenever you hear a word from my mouth, you must warn them on my behalf.
