1 Kings 1:3-7

So they sought for a fair damsel throughout all the coasts of Israel, and found Abishag a Shunammite, and brought her to the king.

And the damsel was very fair, and cherished the king, and ministered to him: but the king knew her not.

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.

And his father had not displeased him at any time in saying, Why hast thou done so? and he also was a very goodly man; and his mother bare him after Absalom.

And he conferred with Joab the son of Zeruiah, and with Abiathar the priest: and they following Adonijah helped him.
