7On the twenty-fourth day of the eleventh month, the month of Shebat, in the second year of Darius, the word of the Lord came to the prophet Zechariah son of Berekiah, the son of Iddo.
8During the night I had a vision, and there before me was a man mounted on a red horse. He was standing among the myrtle trees in a ravine. Behind him were red, brown and white horses.
Zechariah 1:7-8 NIV
And here's the parallel in Revelation 6
1I watched as the Lamb opened the first of the seven seals. Then I heard one of the four living creatures say in a voice like thunder, “Come!” 2I looked, and there before me was a white horse! Its rider held a bow, and he was given a crown, and he rode out as a conqueror bent on conquest.
3When the Lamb opened the second seal, I heard the second living creature say, “Come!” 4Then another horse came out, a fiery red one. Its rider was given the power to take peace from the earth and to make people kill each other. To him was given a large sword.
5 When the Lamb opened the third seal, I heard the third living creature say, “Come!” I looked, and there before me was a black horse! Its rider was holding a pair of scales in his hand. 6Then I heard what sounded like a voice among the four living creatures, saying, “Two pounds of wheat for a day’s wages, and six pounds of barley for a day’s wages, and do not damage the oil and the wine!”
7When the Lamb opened the fourth seal, I heard the voice of the fourth living creature say, “Come!” 8I looked, and there before me was a pale horse! Its rider was named Death, and Hades was following close behind him. They were given power over a fourth of the earth to kill by sword, famine, and plague, and by the wild beasts of the earth.
Revelation 6:1-8 NIV
Between the two passages, there are similarities of horses and those of red and white coloring. The pale, brown, and black shades of horses do not repeat or correlate between the two passages. So are the riders on the horses the same or similar between both passages?
