“[If] guests have been reclining [and eating] by the owner of the house (i.e. a private person) and the day was over (i.e. Friday was over and Shabbat began), as soon as it gets dark they interrupt [their meal, say Birkat Hamazon (Grace After Meals) and go] to the Bet Midrash (Study Hall) [to pray]. [After that] they come back [from the Bet Midrash to the house], they (i.e. the servants) pour for them a cup [of wine and] they say over it Kiddush (Sanctification) of the day (i.e. Friday night Kiddush).” [These are] the words of Rebbi Yehudah. Rebbi Yossi says, “He continues eating [his Friday afternoon meal] from when it gets dark [and on].”
