2 Samuel 3:26

And when Joab was come out from David,.... Which perhaps he did at once, as soon as ever he had spoken his mind, and flew out of the room in a great passion, not waiting for the king's answer, since we read of none returned; though it may be the king disdained to give him one, or cared not to confer with him while in his passion, until it subsided; or chose not to provoke him more, for it is plain he had great power over him; which generals of armies at this time very much assumed, see 2 Samuel 3:39;

he sent messengers after Abner; in the name of the king, as Abarbinel rightly supposes, and so Josephus f; for otherwise it can hardly be thought he would have returned on a message from Joab only, who he knew bore him ill will:

which brought him again from the well of Sirah; which might have its name from the thorns and briers that grew about it. Josephus g calls it Besira, and says it was twenty furlongs or two and an half miles from Hebron:

but David [knew] it not; that Joab had sent messengers in his name after Abner to fetch him back; it was not done by his order, with his consent or knowledge; this is observed, to clear David from any concern in the death of Abner, as follows.
