Revelation 6:1

And when he had opened the third seal, I heard the third beast say, Come and see. And I beheld, and lo a black horse; and he that sat on him had a pair of balances in his hand.

And I saw in the right hand of him that sat on the throne a book written within and on the backside, sealed with seven seals.

And when he had opened the fourth seal, I heard the voice of the fourth beast say, Come and see.

And I heard a voice from heaven, as the voice of many waters, and as the voice of a great thunder: and I heard the voice of harpers harping with their harps:

And I heard as it were the voice of a great multitude, and as the voice of many waters, and as the voice of mighty thunderings, saying, Alleluia: for the Lord God omnipotent reigneth.

And when he had opened the second seal, I heard the second beast say, Come and see.

And the temple of God was opened in heaven, and there was seen in his temple the ark of his testament: and there were lightnings, and voices, and thunderings, and an earthquake, and great hail.

For we cannot but speak the things which we have seen and heard.
