peccatoribus (Ave Maria in French)

Hey all!

I'm trying to understand where we got the "pauvres" in "pauvres pécheurs" when we're reciting Ave Maria in French.
The reason I'm asking is that in Latin it's "Sancta Maria, Mater Dei. Ora pro nobis peccatoribus..." and there is no "pauperes/miseri" at all in there

Thank you all!
