What turned up
Popularly attributed to Tubman; Wikiquote's own citation traces it to Charles Blockson's The Underground Railroad (1987), a secondary compilation, not to Bradford's 1886 'Harriet, the Moses of Her People' as previously recorded — the phrase is absent from Bradford's actual 1886 text.
