To fully understand what is happening, it is useful to recognize where various events occur. The apostle John
is in the Temple of God, because the book with the seals are in God's hand (Rev 5:1),
and when Jesus takes it, the 24 elders surrounding God's throne bowed down to Him (Rev 5:8).
When the first seal is broken, a seraph calls out a white horse whose rider is given a bow and crown. The
white horse rider is tasked with conquering and to conquer; he promotes wonton annihilation and subjugation.
This is not the first mention of colored horses and their riders.
In Zechariah's first vision (Zech 1:7-11), white horses
follow a red horse while patrolling the earth and their riders were angels.
In Zechariah's eighth vision (Zech 6:1-8), he sees four
chariots, which are the four spirits of heaven. These four chariots / spirits of heaven are angels
(2 Ki 6:15-17; Ps 68:17;
Isa 66:15). Going forth between standing before God and patrolling the
earth, the third chariot, being pulled by white horses, follows the chariot with black horses to the "north
country" to appease God's wrath.
Without much detail, it is difficult to understand Zechariah' prophecies; however, one can gain a better
understanding of the colored horses and their riders who emerge with the breaking of the first four seals,
and they all work in concert.
