Reset iterator in loop after erase

I am trying reset an iterator after it has been erased by going

while (vBegin != vEnd)
{ 
    //some stuff; 
    vectorThing.erase(vbegin); 
    vbegin = vectorThing.being();
    vEnd = vectorThing.end();
}

This causes vEnd to equal the thing I just deleted, how do I get it to point to the very end like it was before?
