The major focus of Rev 19:1-10 is the marriage supper of the Lamb (vv. 6-10). This meal, a celebration of the victory over the Beast and his followers, is the climax of an ancient Old Testament motif: the “meal with God” or communal meal in God’s house where the Lord is present with his people. Old Testament examples include Genesis 18; Exod 24:9-11, while New Testament instance run from the feeding of the 5,000, the Last Supper, and celebration of the Lord’s Table. The marriage supper of the Lamb is the final eschatological, messianic banquet, an event that includes believers from every tribe and nation.
