What is the rocket's gas pushing on/ exerting a force on in order to move forward?

NEWTON’S THIRD LAW STATES THAT EVERY ACTION HAS AN EQUAL AND OPPOSITE REACTION
To stop or slow down an object, a force must be applied in the direction opposite to that of the object’s motion. Exerting a force results in an equal force in the opposite direction (like the recoil a person feels when firing a gun).
When a spacecraft fires a thruster rocket, the exhaust gas pushes against the thruster and the thruster pushes against the exhaust gas. The gas and rocket move in opposite directions.
