The Great American Eclipse of August 21, 2017, is a major – huge – harbinger.

When the eclipse begins on August 21, the sunrise will be dark, just as Isaiah predicts.

The Moon involved is called a black moon.

These occur about every 33 months. In the Bible, the divine name of Elohim appears 33 times in Genesis.

The eclipse will start in Lincoln Beach, Oregon - the 33rd state - and end on the 33rd degree of Charleston, South Carolina.

Such a solar eclipse has not occurred since 1918, which is 99 years - or 33 times three.
