Daniel 7:15-16

Even though Daniel understood all kinds of visions and dreams (Daniel 1:17), much of what he had just seen baffled and alarmed him (cf. Daniel 7:28). He now saw himself participating in the events of his vision. He evidently addressed his question to an angel (cf. Daniel 8:16; Daniel 9:21). The fourth beast, and particularly the little horn, were the parts of the vision that he could not understand and most interested him.
