I believe the general sentiment...
of the Founding Fathers was that specific term limits were not necessary. I don't have any quotes to give you, sorry.
The Founders (as I was always led to believe) felt that Govt service was an imposition on the lives of citizens (although a necessary one), and that after service, representatives would leave Govt and return to their normal lives.
And that the fact that we had regular and frequent elections provided all the limitation needed.
Consider this, Washington was actually offered Kingship, and refused it. With this sterling example in front of them, the mood of the times came to favor idividual representatives who voluntarily limited their service to one or two terms.
Consider, also, that one of the big sticks we have to hold politicians accountable is their hope of re-election. A quick look at the actions of some "lame-duck" politicians, since they know they will not be re-elected, and you find some of the worst actions possible.
