This is not even from T. Jefferson. This quote is said by some polish Duke, which was translated to English later.

"Under such a constitution above all, the citizen should arm himself with strength and constancy, and say, every day of his life, what a virtuous Count Palatine said in the Diet of Poland: Malo periculosam libertatem quam quietum servitium."
/ Rousseau, Du Contrat Social (Chapter IV. Democracy)
