With hearts fortified with these animating Reflections, we most solemnly, before God and the World, declare, that, exerting the utmost Energy of those Powers, which our beneficent Creator hath graciously bestowed upon us, the Arms we have been compelled by our Enemies to assume, we will, in defiance of every Hazard, with unabating Firmness and Perseverance, employ for the preservation of our Liberties; being with one Mind resolved to die Freemen rather than to live Slaves.

Thomas Jefferson (1743-1826) American political philosopher, polymath, statesman, US President (1801-09)

Final version as approved by the Continental Congress. An earlier draft by Jefferson used these terms:

We do, then, most solemnly before God and the world declare that regardless of every consequence, at the risk of every distress, the arms we have been compelled to assume we will use with perseverance, exerting to their utmost energies all those powers which our Creator hath given us to preserve that liberty which he committed to us in sacred deposit and to protect from every hostile hand our lives and our properties.
