1 Kings 1:5, 25

Then Adonijah the son of Haggith exalted himself, saying, I will be king: and he prepared him chariots and horsemen, and fifty men to run before him.

For he is gone down this day, and hath slain oxen and fat cattle and sheep in abundance, and hath called all the king's sons, and the captains of the host, and Abiathar the priest; and, behold, they eat and drink before him, and say, God save king Adonijah.
