The Rashbi wrote many juicy and judicious quotes, and today's attack has brought to my mind two of them.
1. Best of snakes cut off its head.
2. If the people of Israel would observe but two Sabbaths properly, G‑d would redeem them immediately!
I think with just one Sabbath it would be more than enough. But, if in Rashbi's time he was one of the few who still knew its correct meaning, today it already belongs to the old and forgotten wisdom that even children knew by heart.
