Eruvin 18 - August 27, 7 Elul

How far/close can one distance the beams for the well from the well? Is there a difference between a well (from a spring) and a cistern (rain water)? Does it make a difference if it belongs to an individual or if it is communal? What is the approach of Chanania, Rabbi Akiva and Rabbi Yehuda ben Bava and is it clear that our mishna doesn't hold like each of them? What is the etymology of the word diomed? The gemara then brings a few other words relating to the root "dio", meaning two. In this conext the gemara brings eight statements of Rabbi Yirmia ben Elazar (one will be in the next daf). 1. Man was created as two images of man and woman and then split. The gemara then brings a debate regarding this issue (was woman created from an appendage/tail of man) and analyzes/questions the different approaches. The gemara is grappling with the differences of the description of the creation of woman from Chapter 1 and Chapter 2 in Genesis. 2. When Adam was excommunicated after he sinned, he gave birth to evil spirits. 3. Don't say all the praise of a person to his/her face. 4. Better to be fed bitter food by the hand of God than to have sweet food given to you by other people (be dependent on others for food). 5. If those in the house learn Torah at night, the house will not be destroyed. 6. Once the Temple was destroyed, the full name of God was no longer used - only the two letters that spell "yah". 7. When Babylonia was destroyed, it affected the neighbors negatively but when the capital of the Israelite kingdom was destroyed it affect the neighboring area positively.
