MISHNAH. R. ELIEZER RULED: IF A FESTIVAL DAY IMMEDIATELY PRECEDES OR FOLLOWS THE SABBATH A MAN MAY PREPARE TWO ERUVS AND MAKE THE FOLLOWING DECLARATION: MY ERUV FOR THE FIRST [DAY SHALL BE THAT] OF THE EAST AND THE ONE FOR THE SECOND DAY THAT OF THE WEST’; ‘THE ONE FOR THE FIRST DAY [SHALL BE THAT] OF THE WEST AND THE ONE FOR THE SECOND DAY THAT OF THE EAST;
‘MY ERUV [SHALL BE EFFECTIVE] FOR THE FIRST DAY, AND FOR THE SECOND DAY [I SHALL RETAIN THE SAME RIGHTS] AS THE PEOPLE OF MY TOWN’, OR ‘MY ERUV [SHALL BE EFFECTIVE] FOR THE SECOND DAY, AND FOR THE FIRST DAY [I SHALL RETAIN THE SAME RIGHTS] AS THE PEOPLE OF MY TOWN —
THE SAGES, HOWEVER, RULED: HE EITHER PREPARES AN ERUV FOR ONE DIRECTION OR NONE AT ALL; HE EITHER PREPARES ONE ERUV FOR THE TWO DAYS OR NONE AT ALL.
The placement of an eruv meal, as we have seen, allows a person to travel from one 2000 cubit limit to another on Shabbat. This method allows travel in both directions over succeeding Shabbat and Festival days.
‘Do you not agree’, they again said to R. Eliezer, ‘that It is forbidden to prepare an eruv for the Sabbath on a festival dayfor the first time?’ ‘Indeed [I do]’, he replied. ‘Surely, then’, [they retorted: ‘the two days must be] one entity of holiness’.
And R.Eliezer? — [The restriction] there is due [to the prohibition] of preparing [for the Sabbath on a festival day].The decision is split. One day two days long or two days each one day long?
