First of all, let me clarify what I mean by "Word of Knowledge" to avoid confusions. I'm particularly interested in the following definition from Wikipedia:
[...] It can also be defined as knowing the secrets of another person's heart [...]
Or in my own wording:
Person A receives a "download" of very specific private/sensitive information about person B, which person B has not shared with anyone up to that point or at least there is no way person A could've known that information. Person A discloses these revelations to person B together with some encouraging message, and person B reacts with shock, typically expressing their bewilderment with phrases like "How did you know that?!!!!".
In my investigations I've come across a handful of anecdotes that more or less match this definition (e.g. 1, 2). For example, I remember the case of a preacher A approaching a person B and telling them something along the lines of "do you remember when you woke up at 4:00 am in your room on this specific date, you stood up and did these specific actions, and then you asked God these specific things? The Lord is telling me that ..." while person B broke into tears as their secrets were revealed with astonishing accuracy. When I come across anecdotes of "word of knowledge" like this, I can't help but feel very impressed. However, my personal impression is that these sorts of anecdotes are relatively uncommon, and I'm having a hard time recalling a case that didn't happen in the context of a Pentecostal or Charismatic denomination.
Question: Are there recorded occurrences of "words of knowledge" outside of denominations that label themselves as Pentecostal or Charismatic? Say, a Baptist missionary receiving a "word of knowledge" in the jungle which led to an unconverted accepting Christianity, etc.
