And so one needs to differentiate: with a lit candle, and a made-up bed, and with a set table, just like this: if he was accustomed, on weekdays, to light a candle with one wick, he should add a second on the Sabbath. And of the table: if he was accustomed to bless ‘Hamotzi’ on one bread, then on the Sabbath he should add a second, so that they are like ‘the double bread’ of the manna.xcviSee BT Shabbat 117b Of the bed, it has been stated, that if he was accustomed ‘to sexually service’ on weekdays, in the midst of argument with his wife and with separation of minds, then he should not couple with his wife on the Sabbath, except in peace. And because of this: ‘The sexual schedule of scholars, is from Sabbath eve to Sabbath eve’.xcviiBT Ketubot 62b
