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 prophecy states each pair twice and puts precept first; this verse states each once and puts line first. Six words run identical at the close, 'here a little, and there a little'. 'line upon line, precept upon precept' stands at exactly three distinct frozen verses in the corpus: 2 Nephi 28:30, D&C 98:12, and this verse - all three in the line-first order, against the prophecy's precept-first. The prophecy states the same formula a second time, with a consequence attached, at Isaiah 28:13. Counts are of distinct frozen verses in the corpus, derived by search at the time of writing.
