Jamieson-Fausset-Brown Bible Commentary

I have found a man--Like all courtiers, in announcing agreeable tidings, he ascribes the merit of the discovery to himself [JEROME]. So far from it being a discrepancy, that he says nothing of the previous understanding between him and Daniel, or of Daniel's application to the king (Dan 2:15-16), it is just what we should expect. Arioch would not dare to tell an absolute despot that he had stayed the execution of his sanguinary decree, on his own responsibility; but would, in the first instance, secretly stay it until Daniel had got, by application from the king, the time required, without Arioch seeming to know of Daniel's application as the cause of the respite; then, when Daniel had received the revelation, Arioch would in trembling haste bring him in, as if then for the first time he had "found" him. The very difficulty when cleared up is a proof of genuineness, as it never would be introduced by a forger.
