This connection's citations are checked against the source text.
The mark sits beside every quote a connection carries. It reports one thing: those words were found in the frozen source text at the reference this page cites, allowing only typographic differences such as curly quotes, dash forms and spacing.
It is not a tier signal, and it is not a judgment about the connection. Where a card carries the Interpretive badge, the reading is still offered with its evidence for you to weigh — the mark speaks only to the citations.
The badges and the mark are separate signals: Textual and Interpretive name the kind of claim a connection makes, while the mark reports that the connection's citations were checked.
The verse names its source: "according as it is spoken by the mouth of Ezekiel the prophet". The chain, reported as textual fact: a search of all 48 frozen Ezekiel chapters finds no occurrence of "whore of all the earth" — though Ezekiel 16 and Ezekiel 23 carry the frozen Old Testament's densest whoredom-and-harlot imagery, applied there to named cities, so what is absent from Ezekiel is the phrase and the church-figure, not the image; the phrase "great and abominable church, which is the whore of all the earth" stands in 1 Nephi 22:13, which is the pairing shown. What that pattern means for the sources these texts drew on is not asserted; the wiki reports where the wording stands and where it does not.
