Worf's line "The Prophets are the only thing keeping the Dominion from coming through the wormhole" establishes that the Dominion has still not brought any reinforcements from the Gamma Quadrant.
This episode represents the first time the Prophets are seen outside the wormhole, and it also represents their fifth appearance in the show (after "Emissary", "Prophet Motive", "Accession" and "Sacrifice of Angels") and Sisko's fourth encounter with them (all previous mentioned, except "Prophet Motive").
The phrase "Eat, drink and be merry, for tomorrow we die," quoted by Quark and Bashir, is a common conflation of two quotations from the Bible: "Eat, drink and be merry" from Ecclesiastes 8:15, and "Eat and drink, for tomorrow we die" in both Isaiah 22:13 and 1 Corinthians 15:32.
Dax states that the tablet says "The Bajorans will suffer horribly... or eat fruit." In the scene between Kira and Odo near the beginning of the episode, Kira is eating fruit salad.
Louise Fletcher (Winn Adami) is not credited as "special guest star" for this episode as is typical.
