1 Kings 1:5-6

5Then Adonijah the son of Haggith exalted himself, saying, “I will be king”; and he prepared for himself chariots and horsemen, and fifty men to run before him.

6(And his father had not rebuked him at any time by saying, “Why have you done so?” He was also very good-looking. His mother had borne him after Absalom.)
