Daniel 9:21-23

while I was still speaking in prayer and extremely exhausted, the man Gabriel, whom I had seen in the earlier vision, came to me about the time of the evening sacrifice. [Dan 8:16] He instructed me and he talked with me and said, “O Daniel, I have now come to give you insight and wisdom and understanding. At the beginning of your supplications, the command [to give you an answer] was issued, and I have come to tell you, for you are highly regarded and greatly beloved. Therefore consider the message and begin to understand the [meaning of the] vision.
