here's the entire quote:
A people who would stand fast in their liberty, should furnish themselves with weapons proper for their defence, and learn the use of them. It is indeed an hard case, that those who are happy in the blessings of providence, and disposed to live peaceably with all men, should be obliged to keep up the idea of blood and slaughter, and expend their time and treasure to acquire the arts and instruments of death. But this is a necessity which the depravity of human nature has laid upon every state. Nor was there ever a people that continued, for any considerable time, in the enjoyment of liberty, who were not in a capacity to defend themselves against invaders, unless they were too poor and inconsiderable to tempt an enemy.
