1. Who it was that asked the question. Daniel had had a vision of Christ in his glory, the man clothed in linen, ch. x. 5. But his discourse had been with the angel Gabriel, and now he looks, and behold other two (v. 5), two angels that he had not seen before, one upon the bank of the river on one side and the other on the other side, that, the river being between them, they might not whisper to one another, but what they said might be heard. Christ stood on the waters of the river, (v. 6), between the banks of Ulai; it was therefore proper that the angels his attendants should stand on either bank, that they might be ready to go, one one way and the other the other way, as he should order them. These angels appeared, (1.) To adorn the vision, and make it the more illustrious; and to add to the glory of the Son of man, Heb. i. 6. Daniel had not seen them before, though it is probable that they were there; but now, when they began to speak, he looked up, and saw them. Note, The further we look into the things of God, and the more we converse with them, the more we shall see of those things, and still new discoveries will be made to us; those that know much, if they improve it, shall know more. (2.) To confirm the discovery, that out of the mouth of two or three witnesses the word might be established. Three angels appeared to Abraham. (3.) To inform themselves, to hear and ask questions; for the mysteries of God's kingdom are things which the angels desire to look into (1 Pet. i. 12) and they are known to the church, Eph. iii. 10. Now one of these two angels said, When shall the end be? Perhaps they both asked, first one and then the other, but Daniel heard only one.
