Blood, sweat and tears

[JPablo]

Where this "blood, sweat and tears" 'expression' comes from?

I remember Spanish poem that goes,

Al destierro con doce de los suyos, polvo, sudor y hierro, el Cid cabalga...

Which is gives a similar "suffering" feeling.
Of course, in Spanish we say too, "sangre, sudor y lágrimas" but I was just wondering if these "normal collocation" has some specific known origin...
