can you confirm this quote?

I just read a quote,supposedly?, by Thomas Jefferson. If it is actually his words I think it answers the question as to what the framers really ment.

“No man shall ever be debarred the use of arms. The strongest reason for the people to retain the right to keep and bear arms, is as a last resort, to protect themselves against tyranny in government.”
Thomas Jefferson, June 1776

His words or not?

It seems pretty believable, and makes the following claim:

I searched the Thomas Jefferson Papers at the Library of Congress, and found the phrase “bear arms” in only 4 documents. None of these is anything like the quotation you gave.

thank you lucwarm and bibliophage
