With what force does the weight of a body numerically coincide? According to Newton’s third law?

The forces with which any two bodies interact are always equal in magnitude and opposite in direction. This is called Newton’s third law in physics. It follows from this that the weight of the body, that is, the force with which the body presses on its support, coincides in magnitude with the force acting from the support on the given body. The force with which the support presses on the body on it is called the reaction force of the support.
