1. This plaque brings darkness over the whole earth. This is the extreme opposite of the last plague – from one extreme to another.
2. It would seem that these plagues follow one another in close order. One plague does not cease when another begins because these people are still suffering from the sores of plague number one when plague number five falls on them.
This chapter presents a horrible picture of the closing days of this age: men and women living with their bodies covered with sores, drinking bloody water, suffering intense heat, in a world turned into total darkness.
We might close this lesson by reading John 1:45.
