In context
1Now King David was old and well along in years, and though they covered him with blankets, he could not keep warm. 2So his servants said to him, “Let us search for a young virgin for our lord the king, to attend to him and care for him and lie by his side to keep him warm.” 3Then they searched throughout Israel for a beautiful girl, and they found Abishag the Shunammite and brought her to the king. 4The girl was unsurpassed in beauty; she cared for the king and served him, but he had no relations with her.
