1 Kings 1:42

And while he yet spake, behold, Jonathan the son of Abiathar the priest came: and Adonijah said unto him, Come in; for thou art a valiant man, and bringest good tidings.

While Adonijah was still speaking in the course of his attempt to take the throne for himself, Jonathan the son of Abiathar the priest arrived on the scene. Adonijah greeted him as a valiant man and took his coming to mean that he carried good tidings in his favor. The message Jonathan brought was the opposite of what was expected, exposing that the conspiracy had collapsed and that Solomon had been proclaimed king instead.
