1 Kings 1:15
King James Version (1769 Blayney revision, with Apocrypha) · Berean Standard Bible
And Bath–sheba went in unto the king into the chamber: and the king was very old; and Abishag the Shunammite ministered unto the king.
So Bathsheba went to see the king in his bedroom. Since the king was very old, Abishag the Shunammite was serving him.
