割以分民,而益其爵祿,是以上得地而民知富,上失地而民知貧,古之所謂致師而戰者,其此之謂也。
If you divide land so as to distribute it among the people and increase the people’s ranks and stipends, then they will know that, when you gain territory, they will grow wealthier and that, when you lose territory, they will grow poorer.
The old expression ‘inciting an army to combat’ refers to this principle.
