One of the korbanot described in Parshat Tzav is the korban mincha, the meal offering. One of the laws regarding this offering was that the Kohanim had to eat it on the premises of the Temple. The words the Torah uses to describe this laws is (Vayikra 6:9) "matzot tei'acheil b'makom kadosh," literally translated as: it shall be eaten unleavened in a holy place.
The Radomsker Rebbe said that one fulfills this verse by guarding the sanctity of his speech, because the verse means that one should make his mouth a "holy place" by guarding his tongue. It is known that Rabbi Yisroel Salanter used to sigh and say, "I wonder about those people who are so careful about what they put into their mouths but pay no attention what comes out of their mouths."
