Revelation 19:6–10 introduces the marriage supper of the Lamb, occurring immediately before the commencement of Jesus’ millennial reign on the earth. Jesus spoke about marriage suppers in Matthew 22:1–14 and 25:1–13. He specifically referred to feasting in the kingdom of heaven, with many from the east and the west, including Abraham, Isaac, and Jacob (Matthew 8:11). The announcement of the marriage supper of the Lamb precedes Jesus’ return to earth to judge His enemies and to establish His kingdom (Revelation 19:11–21).
