Eruvin 58


(a) What do we learn from the Pasuk in Terumah "Orech he'Chatzer ... ve'Rochav Chamishim *ba'Chamishim*."?

(b) What else do we learn from this phrase? How can we learn two things from the same word?

(c) One uses a rope made of Afaskima (alias Nargila).
What does that mean?

(d) What is the alternative explanation - brought later in a Beraisa?

(a) If the best 'rope' is one made of metal chains, why is it not used to measure the Techum?

(b) Then how will we explain the Pasuk in Yechezkel "u've'Yad ha'Ish Keneh ha'Midah"?

(c) Why did they tie the Red Hefer (prior to burning it) specifically with a reed rope?

(d) They tied a rope of 'Netzarim' above the Sotah's breasts.
What are the two meanings of 'Netzarim'?

(a) What do the measurers do if they encounter a high wall whilst measuring?

(b) What does 'Makdir ve'Oleh, Makdir ve'Yored' mean?

(c) This was the method of measuring used when measuring a Gei Me'ukam.
What does 've'Im Hayah Gei Me'ukam' mean?

(d) Which explanation does Rashi reject?

(a) When do we measure 'a wall' (either by Havla'ah or by Kidur), and when do we just asses its width?

(b) What does 'Chut ha'Mishkoles Yored Kenegdo' mean?

(c) What will be the Din in that case?

Answers to questions



(a) With regard to the Din of Mavli'a, Rav Yosef gives the maximum depth of a wadi as two thousand Amos (See the Ritva, who gives a reason for this).
How does one measure, if it is deeper than that?

(b) How can Rav Yosef say that, when the Beraisa gives the maximum depth as a hundred Amos?

(c) In the second Lashon, Rav Yosef permits Havla'ah even when the wadi is *more* than two thousand Amos deep.
How will he reconcile this with Acherim and the Rabbanan, neither of whom give that measurement?

(a) How does Rava differentiate between a hill or a mountain whose gradient is 10 in 24 (ten Tefachim in *four* Amos), and one which is 10 in 30 (ten Tefachim in *five*)?

(b) Rav Huna Brei de'Rav Yehoshua (using the same measurements) explains Rava more leniently.
What does he say?

(a) What size rope does one use for Kidur?

(b) How do the two measurers do Kidur?

(c) How does one measure hills with regard to Eglah Arufah and Ir Miklat?

(d) Does the fact that Ir Miklat is a matter of Piku'ach Nefesh make any difference?

(a) Who is eligible to measure Techumin?

(b) What does one do if the marker at the south-east corner does not correspond with the one on the south-west?

(c) Who is believed to give testimony as to where the Techum of a town ends?
