ו ולוי אמר שני מעיינות הן נסתם הטמא נפתח הטהור נסתם הטהור נפתח הטמא:
6 then ceased for twenty four hours [lit., 'from time to time' — from an hour on one day to the same on the next]. and then gave birth, she is regarded as a woman bearing with a gonorrhoeic discharge: this is R. Eliezer's opinion. R. Joshua said, [The cessation must be] a night and a day, as the night and day of the Sabbath. The cessation referred to is cessation from labour, not from blood[-discharge].<span class="x" onmousemove="('comment',' Nid. 36b. As was stated on p. 577 n. 2, if a woman has blood discharges on three days within the eleven between the menses, she becomes a zabah. If however, this is caused by labour pangs, she is not a zabah, providing however, that her travail continues until giving birth. But if three days of labour and discharge are succeeded by one day free from pain, and then she gives birth, the interruption proves that the issue of the first three days was not the result of labour, but of gonorrhoea, and hence she is a zabah, and subject to the laws thereof, which supersede those of childbirth, the issue during the sixty-six days (v. p. 578) being considered unclean. Now, R. Eliezer and R. Joshua differ as to the meaning, of 'one day'. R. Eliezer maintains that it means a day of 24 hours; but R. Joshua holds that it is a calendar day. i.e., a night and a day. E.g., if she was free from pain from 12 noon on one day to 12 noon on the next, according to R. Eliezer she is a zabah. But on the view of R. Joshua, since she had suffered on the same day. viz., until 12 noon it is not a complete day of cessation, and hence she is not a zabah. As a zabah, cohabitation may be forbidden her on pain of extinction when for mere confinement it would be permitted. ');"><sup>6</sup></span>
