Keep it.

Ah, well, many turns now. We are writing you for what may be the
last time in order to give you back your promised word of support. It is
not little that we have achieved in the indigenous struggle, and that
has been - as we have told you in public and in private - because of
your help. We believe you can be proud, without any shame, of all the
good that we zapatistas, along with you, have built up to this point.
And know that it has been an honor, undeserved in any light, that
people like you have walked at our side.

Keep it. My support is yours till the struggle is over.

Guárdelo. Mi ayuda es la tuya hasta que la lucha encima.
