2 Samuel 13:21

And he, &c. This is not in Hebrew, &c., nor in St. Jerome's version. Josephus and some copies of the Septuagint read it. But the reason here alleged would not suffice to excuse David. (Calmet) --- He might think that, as he had shewn such a bad example himself, he could not with a good grace punish others. (Sanctius) --- This however was requisite, as long as he was king. Whatever faults he might have fallen into, he was not on that account to suffer crimes to remain unpunished; (Haydock) and it is supposed that he testified his resentment to Amnon; (Salien, &c.) though the Scripture be silent thereon. (Haydock) --- Abulensis condemns him for too great remissness. (Menochius)
