Revelation 6:8-10 Holman Christian Standard Bible (HCSB)
8 And I looked, and there was a pale green[a] horse. The horseman on it was named Death, and Hades was following after him. Authority was given to them[b] over a fourth of the earth, to kill by the sword, by famine, by plague, and by the wild animals of the earth.
The Fifth Seal
9 When He opened the fifth seal, I saw under the altar the people[c] slaughtered because of God’s word and the testimony they had.[d] 10 They cried out with a loud voice: “Lord,[e] the One who is holy and true, how long until You judge and avenge our blood from those who live on the earth?”
