Shabbat

it must mean two thirds of a mil. What is the difference between them? — One half of a sixth. Now, it is the reverse in respect of a bee-hive.  For Rabbah said: A bee-hive of two kors capacity  may be moved; of three kors capacity, may not be moved. But R. Joseph said: Three kors capacity also is permitted; four kors is forbidden. Abaye said: I asked it of Mar  at the time of action,  and he did not permit one [to move] even a two-kors size. With whom [does that agree]? — With the following Tanna. For we learnt: A receptacle of stubble, or of staves, and the cistern of an Alexandrian boat, though they have rims and contain forty se'ahs in liquid measure which is two kors in dry measure,  are clean.  Abaye observed: This proves that the heap [in dry measures] is a third. Abaye saw Raba gazing at the West.  Said he to him, But it was taught, 'As long as the face of the east has a reddish glow?' Do you think that the face of the east is meant literally? he replied. [It means] the face which casts a red glow upon the east,  and your token is a window. 'R. Nehemiah said: For as long as it takes a man to walk half a mil from sunset.' R. Hanina said: One who wishes to know R. Nehemiah's period should leave the sun on the top of the Carmel,  descend, dip in the sea, and reascend, and this is R. Nehemiah's period. R. Hiyya said: One who wishes to see Miriam's well should ascend to the top of the Carmel and gaze, when he will observe a kind of sieve in the sea, and that is Miriam's well. Rab said: A moveable well is clean,  and that is Miriam's well. Rab Judah said in Samuel's name: At twilight, as defined by R. Judah, unclean priests may perform tebillah.  According to whom? Shall we say, according to R. Judah [himself]? but it is doubtful!  But if it means twilight, as defined by R. Judah, according to R. Jose; [why state] priests may perform tebillah then-it is obvious! — I might think that twilight, as defined by R. Jose, is a continuation of R. Judah's; [therefore] we are told that R. Judah's twilight ends and then R. Jose's commences. Rabbah b. Bar Hanah said in R. Johanan's name: The halachah is as R. Judah in respect to the Sabbath, and the halachah is as R. Jose in respect to terumah. Now, as for the halachah being as R. Judah in respect to the Sabbath, it is well: this is in the direction of stringency.  But in respect of terumah, what is it? Shall we say, for tebillah?  it is doubtful!
