And the king communed with them,.... He asked them several questions upon the several articles of literature in which they had been educated, to try and see what proficiency they had made; he discoursed with them on various topics of learning, that he might be able to form a judgment of them, and of their capacities, and what employments under him they would be most fit for, and capable of. This shows that the king was a man of learning and good sense, as well as prudence, to be capable of taking such a step as this: and among them all was found none like Daniel, Hananiah, Mishael, and Azariah; for their learning and knowledge: after the king had gone through the examination of all the youths, these four appeared to be the greatest proficients, and were accordingly taken notice of and distinguished: therefore stood they before the king; ministered unto him, became his servants, and even came to be of his privy council, especially Daniel; see Pro 22:29.
