And the Sabbath table should be to the left, and of it is stated:ciibid ‘one who wishes to become wealthy should head northwards.’
The bed should be between north and south.ciiBT Berakhot 5b
And the Sabbath is the sign of the covenant of circumcision, the sign of the phylacteries (tephilin). Whoever desecrates one, it is as if he desecrates the other.
