2 Samuel 16:20

And again, whom should I serve? should I not serve in the presence of his son? as I have served in thy father's presence, so will I be in thy presence.

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.
