'Pertains' in the Bible

So he approached the place where I was standing. As he came, I felt terrified and fell flat on the ground. Then he said to me, "Understand, son of man, that the vision pertains to the time of the end."

Then he said, "I am going to inform you about what will happen in the latter time of wrath, for the vision pertains to the appointed time of the end.

Now I have come to help you understand what will happen to your people in the latter days, for the vision pertains to future days."
