The marriage supper of the Lamb

I've committed to writing brief reflections on daily scripture readings as my goal for the 2025 business year. Today's assigned readings (April 1, 2025) include Psalm 53, Leviticus 25:1-19, and Revelation 19:9-10, with my focus being on Revelation 19:9.

The concept of "the marriage supper of the Lamb" mentioned in this verse is something I'm not entirely familiar with. I recall a seminary class—either constructive theology or liturgy, I can't remember which—where my professor used a film to help us visualize a broader interpretation of the Lord's Supper. Though I can't recall the film's title, and this was over a decade ago, I'm curious about what this marriage supper might entail. I imagine there must be special foods served at such a significant feast.
