創世記 34:25的米示拿參照：Mishnah Ta'anit, Pirkei Avot & Mishnah Shabbat

The men of the maamad fasted on four days of that week, from Monday to Thursday; they did not fast on Friday out of respect for Shabbat or on Sunday in order not to switch from the rest and delight [of Shabbat] to weariness and fasting and [thereby] die. On Sunday [they read], “In the beginning,” and, “Let there be a firmament;” On Monday, “Let there be a firmament,” and, “Let the waters be gathered together;” On Tuesday, “Let the waters be gathered together,” and, “Let there be lights;” On Wednesday, “Let there be lights,” and, “Let the waters swarm;” On Thursday, “Let the waters swarm,” and, “Let the earth bring forth;” On Friday, “Let the earth bring forth,” and, “And the heavens [and the earth] were completed.” For a long section two people read and for a short section one person. [This is how they would read] at Shacharit and Mussaf. And at minhah they assemble and read the section by heart, as they recite the Shema. On Friday at minhah they did not assemble out of respect for Shabbat.

How do we know that if one [a woman] discharges semen on the third day she is unclean? Because it is said, “Be ready for the third day” (Exodus 19:15). How do we know that one who has been circumcised may be bathed on the third day [after circumcision] which falls on Shabbat? Because it is said, “And it came to pass on the third day, when they were in pain” (Genesis 34:25). How do we know that a crimson-colored strap is tied to the head of the goat that is sent [to Azazel]? Because it is said, “If your sins be as scarlet, they shall be as white as snow” (Isaiah 1:18).
