Albert Barnes Commentary Daniel 2:24

"Therefore Daniel went in unto Arioch, whom the king had appointed to destroy the wise men of Babylon; he went and said thus unto him: Destroy not the wise men of Babylon; bring me in before the king, and I will show unto the king the interpretation." — Daniel 2:24 (ASV)

Therefore Daniel went in unto Arioch - In view of the fact that the matter was now disclosed to him, he proposed to lay it before the king. This, of course, he did not do directly, but through Arioch, who was entrusted with the execution of the decree to execute the wise men of Babylon. That officer would naturally have access to the king, and it was proper that a proposal to arrest the execution of the sentence should be made through his agency. The Chaldee דנה כל־קבל kôl - qebēl denâh is, properly, “on this whole account” — or, “on this whole account because” — in accordance with the usually full and redundant mode of writing particles, similar to the German “alldieweil,” or the compound English “forasmuch as.” The meaning is, that in view of the whole matter, he sought to lay the case before the king.

Destroy not the wise men of Babylon - That is, “Stay the execution of the sentence on them. Though they have failed to provide the interpretation demanded, yet, as it can now be given, there is no reason for this severity.” The reason for the sentence was that they could not interpret the dream. As the execution of the sentence involved Daniel and his friends, and as the reason why it was passed at all would now cease because he was able to provide the required explanation, Daniel felt that it was a matter of mere justice that the execution of the sentence should stop altogether.

Bring me in before the king - It would seem from this that Daniel did not consider himself to have free access to the king, and he would not unceremoniously intrude himself into his presence. This verse confirms the interpretation given of (Daniel 2:16), and makes it highly probable that this was the first occasion on which he was personally before the king regarding this matter.
