Daniel 12:6

And one said -One of these angels. It would seem that, though before unseen by Daniel, they had been present, and had listened with deep interest to the communication respecting the future which the angel had made to him. Feeling a deep concern in the issue of these wonderful events - thus evincing the interest which we are taught to believe the heavenly beings take in human affairs (see the notes at1 Peter 1:12) - one of them now addressed him who had been endowed with so much ability to disclose the future, as to the termination of these events. Such an inquiry was natural, and accords with what we should suppose an angel would make on an occasion like this.
