From the engine.

Combustion creates pressure inside the engine, which pushes against all
the walls, and against the front... except there's a big hole in the back,
so nothing presses against the back.

Others have already answered the question well, but I just
wanted to say that this is a question that many people
wondered about or misunderstood in the early days of
rocket development. I think I've read quotes from some
prominent people in those days who, to their embarassment
later, declared publically that rockets wouldn't work in space.

Of course many things about space travel can be a little hard
to understand at first, since vacuums, weightlessness, etc.
are things that we normally don't have to think about in our
daily lives.
