Text of the 2nd Amendment:
 
A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed.

The 2nd Amendment Is What Makes The Other Nine Possible

Here are some quotes from some Founding Fathers:

"I ask, sir, what is the militia? It is the whole people, except for few public officials." - George Mason

"Are we at last brought to such humiliating and debasing degradation, that we cannot be trusted with arms for our defense? Where is the difference between having our arms in possession and under our direction, and having them under the management of Congress? If our defense be the real object of having those arms, in whose hands can they be trusted with more propriety, or equal safety to us, as in our own hands?" - Patrick Henry

"That the said Constitution shall never be construed to authorize Congress to infringe the just liberty of the press or the rights of conscience; or to prevent the people of The United States who are peaceable citizens from keeping their own arms..." - Samuel Adams
 
"Firearms stand next in importance to the Constitution itself. They are the American people's liberty teeth and keystone under independence ... From the hour the Pilgrims landed, to the present day, events, occurrences, and tendencies prove that to insure peace, security and happiness, the rifle and pistol are equally indispensable . . . the very atmosphere of firearms everywhere restrains evil interference - they deserve a place of honor with all that is good" - George Washington

INFRINGED - to encroach upon in a way that violates law or the rights of another
