The most important part of these verses comes in verse 23. The darkness “did last for the space of three days that there was no light seen.” It is not a coincidence that there were three days of darkness as a contrast to three days of light at Christ’s birth. The two miraculous events precisely bookend His life.
The nature of this vapor of darkness also fits with the description of the vapors released by some volcanic eruptions. Similar descriptions have been reported for other volcanic eruptions in history.
