If there is a border or a sea quill plant in the middle of a field, it separates the field regarding certain halachot but not others. \u00a0One case it works for is acquiring land that belonged to a convert who died (hefker). \u00a0One opinion is that is is not considered a separation for carrying on Shabbat and Rava says that it is. \u00a0The exact details about what this means are described in the gemara. \u00a0If there is no border, how much of the field goes to the one who acquired it? \u00a0The gemara then discusses that the sea quill was used by Yehoshua to demarcate borders between the tribes when he conquered\u00a0Israel. \u00a0From there the gemara\u00a0mentions another issue relating to Yehoshua and then one relating to the borders of Israel that Moshe was shown by God right before he died which are the ones that are obligated in tithes. \u00a0The ones excluded from this are the lands that belonged to other neighbors (not from the 7 nations) – the Kini, Knizi and Kadmoni. \u00a0There is a 3 way argument about what geographic areas this is referring to. \u00a0 The next mishna\u00a0and gemara discuss issues regarding testimony about the 3 year chazaka. \u00a0Can 3 groups of witnesses testify each about a separate year? \u00a0Is this considered a whole unit of testimony (which is acceptable) or a part of a testimony (which is not acceptable)?\u00a0 What if 2 witnesses testified about all 3 years but disagreed about which type of produce the person benefitted from? \u00a0Would their testimony be accepted?<\/p>\n
