Whistle Don't Mean Quit

I've been working all lifelong, did I ever let it in Take me to the river, Lord, and float me I been bleeding all my blood till there ain't no red in it If I seem muddy wade to my chin in it If I seem muddy wade to my chin in it Hear them rolling all night long but the whistle don't mean quit Dig my boots in black coal till I'm covered in it The whistle crying aloud don't never mean quit Lord knows I've called his name in the middle of the night and the pouring rain When the blisters on my palms split in He ain't gonna let me down Don't rest them bones or set down just yet If it ain't gonna kill you then you'll move instead The whistle crying aloud don't never mean quit The whistle singing hard don't never mean quit
