2 Samuel 16:21

And Achitophel said to Abessalom, Go in to thy father's concubines, whom he left to keep his house; and all Israel shall hear that thou hast dishonoured thy father; and the hands of all that are with thee shall be strengthened.

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.

Ahithophel said to Absalom, “Go in to your father’s concubines that he has left to keep the house. Then all Israel will hear that you are abhorred by your father. Then the hands of all who are with you will be strong.”
