At minute 1:34 they quote "...prophet Daniel....many shall run to and fro, and knowledge shall increase...." They make two other references in the vid something in Revelation about a world system of commerce and something about the gospel being preached throughout the world before the end.
All of these were done a long, long time ago. There was a world system of commerce multiple times. Knowledge greatly increased, then it flagged, then it increased, then it flagged. Also the gospel, according to Mark 16, was preached to all nations.
First of all I find Mark 16th chapter ends at verse 8.
After verse 8 there are No corresponding reference verses as there is with the rest of Mark.
Plus, the style of writing changes after verse 8.
Jerome and Eusebius both concluded the last chapter of Mark ends at verse 8.
The ' to and fro ' of Daniel 12:4 is talking about roving through, traveling through, the pages of Scripture.
At this time of the end of all badness on Earth people would criss-cross through the Scriptures.
For example: A comprehensive concordance today puts the Bible in ABC order for us to make it possible to help search or research though the pages of Scripture by using a topic or a subject arrangement.
'Modern Technology' has made rapid Bible translation possible to quickly speed up the 'traveling'. - Isaiah 60:22
Speed up the international proclaiming about God's kingdom of Daniel 2:44 as Jesus said at Matthew 24:14; Acts 1:8.
Thus, with accelerating speed we are now at the 'final phase', so to speak, about what Jesus said would be done.
As it is written, so it actually is.
