2 Samuel 16:22

“Thus says Yahweh, ‘Behold, I will raise up evil against you from your own household; I will even take your wives from before your sight and give them to your companion, and he will lie with your wives in the sight of this sun.

‘Indeed you did it secretly, but I will do this thing before all Israel, and before the sun.’”

So the king went out and all his household with him. But the king left ten concubines to keep the house.

Then David came to his house at Jerusalem, and the king took the ten women, the concubines whom he had left to keep the house, and placed them under guard and provided them with sustenance, but did not go in to them. So they were shut up until the day of their death, living as widows.
