1 Kings 1:4

Now King David was old and advanced in years; and they covered him with clothes, but he couldn’t keep warm.

Therefore his servants said to him, “Let a young virgin be sought for my lord the king. Let her stand before the king, and cherish him; and let her lie in your bosom, that my lord the king may keep warm.”

So they sought for a beautiful young lady throughout all the borders of Israel, and found Abishag the Shunammite, and brought her to the king.

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

His father had not displeased him at any time in saying, “Why have you done so?” and he was also a very handsome man; and he was born after Absalom.

He conferred with Joab the son of Zeruiah and with Abiathar the priest; and they followed Adonijah and helped him.
