2 Samuel 16:20-21

King James Version

²⁰ Then said Absalom to Ahithophel, Give counsel among you what we shall do.

²¹ 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.
