Attached is a good list for reference.
A couple of my favorites:
"Firearms stand next in importantce to the constitution itself. They are the American people's liberty teeth and the keystone under independence. The rifle and pistol are equally indispensable. The very atmosphere of firearms anywhere and everywhere restrains evil interference - they deserve a place of honor with all that is good." - George Washington
"Another source of power in government is a military force. But this, to be efficient, must be superior to any force that exists among the people, or which they can command; otherwise, this force would be annihilated on first exercise of acts of oppression. Before a standing army can rule, the people must be disarmed, as they are in almost every kingdom in Europe. The supreme power in America cannot enforce unjust laws by the sword, because the whole body of the people are armed, and constitute a force superior to any band of regular troops that can be, on any pretence, raised in the United States." - Noah Webster
