2 Samuel 16:3

Which though it might seem a very unlikely thing, yet such vain expectations do often get into the minds of men; nor was it impossible, that when David's family was thus divided, and one part engaged against another, they might destroy themselves by mutual wounds; and the people being tired out with civil wars, might restore the kingdom to the family of Saul their old master, whereof this was the top branch. And this was a time of general defection of many whom the king had greatly obliged, witness Ahithophel. And Mephibosheth's absence made the calumny more probable.
