Revelation 6:8

When he opened the third seal, I heard the third living creature saying, “Come and see!” And behold, a black horse, and he who sat on it had a balance in his hand.

I heard a voice in the middle of the four living creatures saying, “A choenix of wheat for a denarius, and three choenix of barley for a denarius! Don’t damage the oil and the wine!”

When he opened the fourth seal, I heard the fourth living creature saying, “Come and see!”

When he opened the fifth seal, I saw underneath the altar the souls of those who had been killed for the Word of God, and for the testimony of the Lamb which they had.

They cried with a loud voice, saying, “How long, Master, the holy and true, until you judge and avenge our blood on those who dwell on the earth?”

A long white robe was given to each of them. They were told that they should rest yet for a while, until their fellow servants and their brothers, who would also be killed even as they were, should complete their course.
