gather together for the great supper: This feast on the flesh of the armies fighting against Christ contrasts with the marriage of the Lamb (Revelation 19:7). The enemies ready for battle are quickly destroyed (Revelation 19:20–21; see also 14:17–20; 16:16–21). Two feasts (the marriage supper of the Lamb in Revelation 19:7–8 and the "great supper" of God's judgment in Revelation 19:17–18, 21) offer two views on the end of time. They show the two sides of the good news:
grace and judgment, and
reward and punishment (compare John 3:16–18).
