2Sam 15.16 And the king went forth, and all his household after him. And the king left ten women, which were concubines, to keep the house.
2Sam 16.21-22 And Ahithophel said unto Absalom, Go in unto thy father's concubines, which he hath left to keep the house; and all Israel shall hear that thou art abhorred of thy father: then shall the hands of all that are with thee be strong.
