והפועלים שתים בשבת: והתניא הפועלים אחת בשבת א"ר יוסי ברבי חנינא לא קשיא כאן בעושין מלאכה בעירן כאן בעושין מלאכה בעיר אחרת תניא נמי הכי הפועלים שתים בשבת במה דברים אמורים בעושין מלאכה בעירן אבל בעושין מלאכה בעיר אחרת אחת בשבת:
For laborers twice a week. But was it not taught: Laborers, once a week? Yose the son of R. Hanina replied: This is no difficulty; the former [refers to laborers] who do their work in their own town while the latter [refers to laborers] who do their work in another town. It was also taught in a baraita: Laborers [are obligated to have sex with their wives] twice a week. To what does this refer? [To those] who do their work in their own town, but for those who do their work in another town [the time is only] once a week.
