“An armed people are a free people. If our forefathers were not armed before the American Revolution we would all be speaking English today.”

Virginia Resolution of 1798 (24 December 1798) http://www.constitution.org/cons/virg1798.htm
Federalist No. 46 (29 January 1788) Full text at Wikisource
1790s
Variant: [The Constitution preserves] the advantage of being armed which Americans possess over the people of almost every other nation (where) the governments are afraid to trust the people with arms.
Context: That the General Assembly doth particularly protest against the palpable and alarming infractions of the Constitution, in the two late cases of the "Alien and Sedition Acts" passed at the last session of Congress; the first of which exercises a power no where delegated to the federal government, and which by uniting legislative and judicial powers to those of executive, subverts the general principles of free government; as well as the particular organization, and positive provisions of the federal constitution; and the other of which acts, exercises in like manner, a power not delegated by the constitution, but on the contrary, expressly and positively forbidden by one of the amendments thereto; a power, which more than any other, ought to produce universal alarm, because it is levelled against that right of freely examining public characters and measures, and of free communication among the people thereon, which has ever been justly deemed, the only effectual guardian of every other right.
Context: Besides the advantage of being armed, which the Americans possess over the people of almost every other nation, the existence of subordinate governments, to which the people are attached, and by which the militia officers are appointed, forms a barrier against the enterprises of ambition, more insurmountable than any which a simple government of any form can admit of. Notwithstanding the military establishments in the several kingdoms of Europe, which are carried as far as the public resources will bear, the governments are afraid to trust the people with arms.

Multitude: War and Democracy in the Age of Empire

2013, Second Inaugural Address (January 2013)
Context: We will defend our people and uphold our values through strength of arms and rule of law.  We will show the courage to try and resolve our differences with other nations peacefully –- not because we are naïve about the dangers we face, but because engagement can more durably lift suspicion and fear. America will remain the anchor of strong alliances in every corner of the globe.  And we will renew those institutions that extend our capacity to manage crisis abroad, for no one has a greater stake in a peaceful world than its most powerful nation. We will support democracy from Asia to Africa, from the Americas to the Middle East, because our interests and our conscience compel us to act on behalf of those who long for freedom.  And we must be a source of hope to the poor, the sick, the marginalized, the victims of prejudice –- not out of mere charity, but because peace in our time requires the constant advance of those principles that our common creed describes: tolerance and opportunity, human dignity and justice.

A further quote sometimes purported to be from a speech to Congress, January 7, 1790 purportedly in the Boston Independent Chronicle, January 14, 1790, this is actually a corruption of a statement made in his first State of the Union Address, relating to the need for maintaining governmental troops and military preparedness:
:: A free people ought not only to be armed, but disciplined; to which end a uniform and well-digested plan is requisite; and their safety and interest require that they should promote such manufactories as tend to render them independent of others for essential, particularly military, supplies.
The proper establishment of the troops which may be deemed indispensable will be entitled to mature consideration. In the arrangements which may be made respecting it it will be of importance to conciliate the comfortable support of the officers and soldiers with a due regard to economy.

Wir wollen sein ein einzig Volk von Brüdern,
in keiner Not uns trennen und Gefahr.
Wir wollen frei sein, wie die Väter waren,
eher den Tod, als in der Knechtschaft leben.
Wir wollen trauen auf den höchsten Gott
und uns nicht fürchten vor der Macht der Menschen.
Act II, Sc. 2, as translated by C. T. Brooke
Variant translation: We shall be a single People of brethren,
Never to part in danger nor distress.
We shall be free, just as our fathers were,
And rather die than live in slavery.
We shall trust in the one highest God
And never be afraid of human power.
Wilhelm Tell (1803)
