2 Samuel 20:3

And David came to his house at Jerusalem, after the outbreak of this rebellion; and the king took the ten women, his concubines, whom he had left to keep the house, 2 Samuel 15:16; 2 Samuel 16:21, and put them in ward, in a house by themselves, and fed, maintained, them, but went not in unto them, for they were impure to him, having been approached by Absalom. So they were shut up unto the day of their death, living in widowhood, in perpetual widowhood.
