Revelation 6:1-8 (NRSV)
1 Then I saw the Lamb open one of the seven seals, and I heard one of the four living creatures
call out, as with a voice of thunder, “Come!” 2 I looked, and there was a white horse! Its rider had a bow; a crown was given to him, and he came out conquering and to conquer.
3 When he opened the second seal, I heard the second living creature call out, “Come!” 4 And out came another horse, bright red; its rider was permitted to take peace from the earth, so that people would slaughter one another; and he was given a great sword.
5 When he opened the third seal, I heard the third living creature call out, “Come!” I looked, and there was a black horse! Its rider held a pair of scales in his hand, 6 and I heard what seemed to be a voice in the midst of the four living creatures saying, “A quart of wheat for a day’s pay, and three quarts of barley for a day’s pay, but do not damage the olive oil and the wine!”
7 When he opened the fourth seal, I heard the voice of the fourth living creature call out, “Come!” 8 I looked and there was a pale green horse! Its rider’s name was Death, and Hades followed with him; they were given authority over a fourth of the earth, to kill with sword, famine, and pestilence, and by the wild animals of the earth.
