I love to find these quotes from Eretz Yisrael, it exposes some of the wisdom that the Babylonian Talmud chooses to associate with the land of Israel. For instance, what is special about Israel that encourages that particular saying? It would seem that this wisdom is applicable anywhere. Certainly we have in Pirkei Avoth, "siyag l'hochmah shtikah" - being silent is a fence around wisdom.
Ironically, everytime I think of something to write regarding this quote.. I feel the urge to be silent.
All I will say is that my grandfather always reminded me how important it is to take the time to think through your words before you let them out of your mouth. Today would have been his seventy eighth birthday, he passed away this year in Heshvan, my favorite month.
[for another example of wisdom from Eretz Yisrael in the Babylonian Talmud, see my post here from Masechet Horayos.]
