Then Arioch brought in Daniel before the king in haste - The Chaldee word used here implies “in tumultuous haste,” as of one who was violently excited, or in a state of trepidation, from בהל bâhal - “to tremble, to be in trepidation.” The trepidation in this case may have arisen from one or both of two causes:
(1) exultation, or joy, that the great secret was discovered; or
(2) joy that the effusion of blood might be stayed, and that there might be now no necessity to continue the execution of the sentence against the wise men.
I have found a man - Margin, as in Chaldee, “That I have found a man It is not to be supposed that Arioch had known anything of the application which Daniel had made to the king to delay the execution of the sentence Daniel 2:16, and, for anything that appears, he had suspended that execution on his own responsibility. Ignorant as he was, therefore, of any such arrangement, and viewing only his own agency in the matter, it was natural for him to go in and announce this as something entirely new to the king, and without suggesting that the execution of the sentence had been at all delayed. It was a most remarkable circumstance, and one which looks like a Divine interposition, that he should have been disposed to delay the execution of the sentence at all, so that Daniel could have an opportunity of showing whether he could not divulge the secret. All the circumstances of the case seem to imply that Arioch was not a man of a cruel disposition, but was disposed, as far as possible, to prevent the effusion of blood.
Of the captives of Judah - Margin, as in Chaldee, “of the children of the captivity.” The word “Judah” here probably refers to the “country” rather than to the “people,” and means that he was among those who had been brought from the land of Judah.
That will make known unto the king the interpretation - It is clear, from the whole narrative, that Arioch had great confidence in Daniel. All the “evidence” which he could halve that he would be able to make this known, must have been from the fact that Daniel “professed” to be able to do it; but such was his confidence in him that he had no doubt that he would be able to do it.
