Revelation 14:19 (ESV)

19 So the angel swung his sickle across the earth and gathered the grape harvest of the earth and threw it into the great winepress of the wrath of God.

The picture is one of aggressive action in the vineyards of the earth so as to accomplish a universal task in short order.
