1 Kings 1:1-3

1 Now King David was old and far on in years; and though they put covers over him, his body was cold.

2 So his servants said to him, Let search be made for a young virgin for my lord the king, to take care of him and be waiting on him; and you may take her in your arms, and so my lord the king will be warm.

3 So after searching through all the land of Israel for a fair young girl, they saw Abishag the Shunammite, and took her to the king.
