the first 4 seals which may have already been broken:

1. Rev 6:1-2

The White Horse. The Antichrist comes forth. He has a bow, but no arrows are mentioned. A crown is given to him. He goes forth conquering and to conquer.

2. Rev 6:3-4

The Red Horse. War.
That they should take peace from the earth. He has a great sword.

3. Rev 6:5-6

The Black Horse. Famine.
A day’s wages for a day’s food. Hurt not the oil and the wine.

4. Rev 6:7-8

The Pale Horse. Death. One-fourth of the earth’s population is killed. Hell followed with him. Kill with the sword, and with hunger, and with death, and with the beasts.
