Revelation 6:4-8

And another, a red horse, went out; and to him who sat on it, it was granted to take peace from the earth, and that people would kill one another; and a large sword was given to him. The Third Seal: Famine

When He broke the third seal, I heard the third living creature saying, “Come!” I looked, and behold, a black horse, and the one who sat on it had a pair of scales in his hand.

And I heard something like a voice in the center of the four living creatures saying, “A quart of wheat for a denarius, and three quarts of barley for a denarius; and do not damage the oil and the wine.” The Fourth Seal: Death

When the Lamb broke the fourth seal, I heard the voice of the fourth living creature saying, “Come!”

I looked, and behold, an ashen horse; and the one who sat on it had the name Death, and Hades was following with him. Authority was given to them over a fourth of the earth, to kill with sword, and famine, and plague, and by the wild animals of the earth. The Fifth Seal: Martyrs
