קבלה על ישעיהו 56:2

Since we find that Rabbi Shimon related the sign of the Brit to the sign of Shabbat, Tefilin and Holidays, it seems that the damage is equal for all of them and we must be cautious with them all. The sages also say that whoever keeps Shabbat with all its laws all of his sins are atoned, as it says “keeping the Shabbat from profaning it (Mechalelo)” (Isaiah 56:2), don’t read Mechalelo but rather Machul Lo (he is atoned).
