This week's Haftorah tells how Dovid HaMelech's son Adoniyahu attempted to illegitimately seize the Kingship which was not rightfully his.
Using falsehood and deception, he caused some of the most respected and influential figures in King David's government to believe that he had been legitimately granted the Kingship.
The presence of the influential figures convinced the masses that his claim to the throne was legitimate, and he arranged a large celebration in anticipation of his ascension to be King, chanting and screaming ''Long Live our King Adoniyahu!"
Despite his brazen attempt to steal the crown - in the process convincing the masses that he was the legitimate heir to the throne - he was not successful, and David made clear who the rightful successor would be [his son Shlomo].
Adoniyahu is the same gematria as Biden [76]
