Revelation 14:17-18

17Then another angel came out from God's house in heaven. He also had a sharp knife in his hand.

18Again, another angel came from the altar where people offered gifts to God. This angel had authority for the fire on the altar. He shouted with a loud voice to the angel who had the sharp knife. He told him, ‘Use your knife and cut the grapes off the earth's vine. The grapes are ready now to make wine.’
