1 Kings 1:3-7

So they searched for a beautiful girl throughout the territory of Israel, and found Abishag the Shunammite, and brought her to the king.

The girl was very beautiful; and she became the king’s nurse and served him, but the king did not become intimate with her.

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

And his father had never rebuked him at any time by asking, “Why have you done so?” And he was also a very handsome man, and he was born after Absalom.

Now he had conferred with Joab the son of Zeruiah and with Abiathar the priest; and they allied themselves with Adonijah.
