Daniel 2:23

Perhaps Daniel referred to Yahweh as the "God of his [my] fathers" because he was experiencing God’s compassion in a similar way that his spiritual forefathers had experienced it. He gave the credit for the wisdom, and its resultant power that he had received, to its proper Source. Daniel did not originate these revelations but received them from God and communicated them to others (cf. 2 Peter 1:21). He viewed the vision as an answer to the prayers of himself and his three friends (Daniel 2:23). He was confident that the information God had given him would save their lives. This confidence is testimony to the clarity and obvious supernatural source of this revelation. Daniel did not need to contrive an answer that he hoped would satisfy the king, as the Babylonian seers did. He simply needed to declare the revelation that the only living and true God had given him.

We should bear this testimony of Daniel in mind when we read the later revelations God gave him in this book. They are as reliable as this one was, because they too came from the God of wisdom and power.
