Then Joab came to the king
To the apartment where he was; perhaps he was told the above at his first entering into the king's palace, by some in waiting, before he came to the king, which filled him with wrath, so that he came to him in a passion:
and said to him, what hast thou done?
which was very insolent in a subject to say to his prince:
behold, Abner came unto thee;
I have been credibly informed of it, and am assured it is a fact which cannot be denied; he represents it as if he had done a wrong thing to admit him to come to him; but perhaps the great fault was that he had let him go:
why [is] it [that] thou hast sent him away, and he is quite gone?
or "going, [is] gone" F5; is clean gone off, when he ought to have been laid hold on as a traitor, and put in irons.
