Revelation 6:8-10 Easy-to-Read Version (ERV)
8 I looked, and there before me was a pale-colored horse. The rider on the horse was death, and Hades was following close behind him. They were given power over a fourth of the earth—power to kill people with the sword, by starving, by disease, and with the wild animals of the earth.
9 The Lamb opened the fifth seal. Then I saw some souls under the altar. They were the souls of those who had been killed because they were faithful to God’s message and to the truth they had received. 10 These souls shouted in a loud voice, “Holy and true Lord, how long until you judge the people of the earth and punish them for killing us?”
