Revelation 6:8-14 AMP

8 So I looked, and behold, an ashy pale horse [black and blue as if made so by bruising], and its rider's name was Death, and Hades (the realm of the dead) followed him closely. And they were given authority and power over a fourth part of the earth to kill with the sword and with famine and with plague (pestilence, disease) and with wild beasts of the earth. [Ezek. 5:12; Hos. 13:14.]

9 When the Lamb broke open the fifth seal, I saw at the foot of the altar the souls of those whose lives had been sacrificed for [adhering to] the Word of God and for the testimony they had borne.

10 They cried in a loud voice, O [Sovereign] Lord, holy and true, how long now before You will sit in judgment and avenge our blood upon those who dwell on the earth? [Gen. 4:10; Ps. 79:5; Zech. 1:12.]

11 Then they were each given a long and flowing and festive white robe and told to rest and wait patiently a little while longer, until the number should be complete of their fellow servants and their brethren who were to be killed as they themselves had been.

12 When He [the Lamb] broke open the sixth seal, I looked, and there was a great earthquake; and the sun grew black as sackcloth of hair, [the full disc of] the moon became like blood. [Joel 2:10, 31.]

13 And the stars of the sky dropped to the earth like a fig tree shedding its unripe fruit out of season when shaken by a strong wind. [Isa. 34:4.]

14 And the sky rolled up like a scroll and vanished, and every mountain and island was dislodged from its place.
