And another angel came out from the altar, which had power over fire; and cried with a loud cry to him that had the sharp sickle, saying, Thrust in thy sharp sickle, and gather the clusters of the vine of the earth; for her grapes are fully ripe.
From the altar - upon which were offered the incense-accompanied prayers of all saints, which bring down in answer God's fiery judgment on the Church's foes, the fire being taken from the altar and cast upon the earth (Revelation 6:9-11; Revelation 8:3-5).
Fully ripe - for punishment х eekmasan (G187)]: 'come to their acme' (Genesis 15:16).
