What does Daniel 12:6 mean?
This extensive vision (Daniel 11:2—12:4) came to Daniel through a heavenly messenger. This being is most likely the angel Gabriel (Daniel 8:15–16; 9:21–22; 10:18-21; Luke 1:26).He appeared above the Tigris River. Now, near the end of the message, two new figures appear (Daniel 12:5).Daniel hears a question being directed towards the figure above the river. Presumably, this is spoken by one of the two newly mentioned beings. It echoes the question posed in an earlier vision (Daniel 8:13): what is the timeline of these events? Most likely, this is a reference to the most recent series of predictions (Daniel 11:36—12:4). It may also be a general question about when all the prophesied events would occur. However, the precise mention of "the end" makes that option unlikely.
The celestial being above the Tigris will provide an answer which is extremely specific in one sense, and very vague in another (Daniel 12:7).
