1 Kings 1:1-4

Now King David was old, advanced in age; and they covered him with garments, but he could not keep warm.

So his servants said to him, “Have them search for a young virgin for my lord the king, and have her attend the king and become his nurse; and have her lie on your chest, so that my lord the king may keep warm.”

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.
