Revelation 14:19-20

19So the angel moved his sharp knife over the earth. He cut off the grapes which grew in the earth's vineyard. He threw the grapes into the winepress where God stamps on the grapes because he is very angry.

20The winepress was outside the city. When God stamped on the grapes, the juice that came out of the winepress was blood. The river of blood was very deep. It rose as high as horses' necks and it went as far as 300 kilometres.
