Nine in the third place means:

A prince offers it to the Son of Heaven.
A petty man cannot do this.

A magnanimous, liberal-minded man should not regard what he possesses as his exclusive personal property, but should place it at the disposal of the ruler or of the people at large. In so doing, he takes the right attitude toward his possession, which as private property can never endure. A petty man is incapable of this. He is harmed by great possessions, because instead of sacrificing them, he would keep them for himself.
