In one of Smith's translations - and I'm 80% certain it's from the 1830 Book of Mormon - he translated "they came a runnin'", "they come a runnin'" or something very similar.
When I search, all I'm finding are LDS sites about how Smith came running through the woods holding the gold plates under one arm.
My LDS research is catalogued as more of a study from "these things did or didn't take place in American history" than 'aha!', so I don't have a "Smith said they came a runnin'" note.
Anybody? Anybody? Bueller? Bueller?
