有一条 《巴拉伊塔》 教导:拉比哈纳尼亚·本·阿卡比亚 说:论书写妥拉经卷、经文护符匣与 门柱经匣 的文士,他们本人、出售这些的商人、从头一批商人那里买来又卖给别人的商人,以及一切从事天之工作的人——这包括出售繸子所用天蓝染料的人——在他们从事那工作时,全都免于诵 《听》 的诫命、免于祷告、免于戴经文护符匣,也免于妥拉里所提的一切诫命。
§ It is taught in a baraita: Rabbi Ḥananya ben Akavya said: With regard to scribes of Torah scrolls, phylacteries, and mezuzot, they themselves, and the merchants who sell them, and the merchants who purchase them from the first merchants and sell them to others, and all who are engaged in the labor of Heaven, which comes to include the sellers of the sky-blue dye for ritual fringes, are all exempt from the mitzva of reciting Shema and from prayer and from donning phylacteries and from all mitzvot that are mentioned in the Torah while they are engaged in that labor.
