2 Samuel 13:30

And it came to pass, while they were in the way, that tidings came to David, saying, Absalom hath slain all the king's sons, and there is not one of them left.

Tidings came to David, saying, Absalom hath slain all the king's sons. It was natural that, in the consternation and tumult caused by so atrocious a deed, an exaggerated report should reach the court, which was plunged into the depths of grief and despair. But the information of Jonadab, who seems to have been privy to the design, and the arrival of the other princes, made known the real extent of the catastrophe.
