It's "Verachatz Besaro BaMayim VeTamei Ad Haarev" :)
But seriously, are questions looking for "sources" with just a question of where to find something on topic?
We've had quite a few questions like this:
- Zohar and Sholom
- The Sifra on peace
- The chachamim on peace
Should we close them?
It seems a lot like the "guessing game" questions. If you don't give me tips on where to find it, or the reason why it's interesting (so that I can look up your sources), I can only do the same thing you can, that's right, Google.
