David came to his house. He took the ten women who kept the house. He kept them safe and fed them, but he did not live with them. They stayed inside all their days.
When David returned to his palace in Jerusalem, he took the ten concubines he had left to take care of the palace, and he placed them in a house under guard. He provided for them, but he no longer slept with them. They were confined until the day of their death, living as widows.
KJV
And David came to his house at Jerusalem; and the king took the ten women [his] concubines, whom he had left to keep the house, and put them in ward, and fed them, but went not in unto them. So they were shut up unto the day of their death, living in widowhood.
