Both of the speeches I handed you fit your description. As do others. You're going to have to be more specific. Washington delivered multiple Addresses to the first session of Congress.
His very first address, to the 1st session of Congress. That's where the quote in question supposedly originated.
That should be the inaugural address. I linked to that (note the date).
Washington's speeches are all transcribed and easily located online. If you put one line from the quote into Google, it should pull the speech it was in without having to know anything other than the quote. It doesn't pull any speeches of his; just sites claiming he said it and others saying he didn't. The statement is too simplistic to come from Washington anyway, in my opinion.
I think it's inarguable that the majority of the founding fathers supported the right to bear arms, and I think there's plenty of valid quotes of theirs that support that. But I think misinformation is nothing but harmful, and I think our media and the internet is full of misinformation. I think it's dragging us down as a country, and causing people to do stupid things. Like show up for basic presidential speeches having nothing to with gun control carrying guns, thinking they're making some sort of brilliant statement. It makes no one listen to anyone else, and both sides get led around by their ears by special interest groups, corrupt politicians, and anyone else with a profit or personal motive for doing so. Drives me nuts.
