Sit and Pause

''Speak to the Children of Israel and let them turn back and encamp before Pi-hachiros'' [Beshalach 14:2]

This verse, said the Ohev Yisrael [R'Avraham Yehoshua of Apta], hints at an important lesson.  

It teaches us just how cautious one has to be not to violate the grave sin of lashon hora.

וְיָשֻׁבוּ וְיַחֲנוּ לִפְנֵי פִּי הַחִירֹת - A person is required to sit [lasheves] and pause for a moment [výachanu] - before [lifnei] he lets his mouth loose [pi hachiros].
