Talmud for Bava Batra 199:11
דרך הרבים שש עשרה אמה: תנו רבנן דרך היחיד ארבע אמות דרך מעיר לעיר שמונה אמות
R. Jose, son of R. Hanina, said: The Sages agree with R. Eleazar in [the case of] a path of vineyards. Since it was made [only] for walking it is acquired by walking. When they came before R. Isaac b. Ammi [with the case of one who sold to another a path in vineyards], he said unto them: Give him [a path so wide] that he may carry [through it] a load of twigs and [be able to] turn round.<span class="x" onmousemove="('comment',' Without touching the fences of the path. ');"><sup>21</sup></span> This, [however], has been said only [in the case] where [the path] is marked out by walls, but when it is not marked out by walls [the width of the path need be only] so much as [to allow him] to lift up one foot and put down the other.<span class="x" onmousemove="('comment',' Since there are no walls, one can carry a load conveniently, however narrow the path may be. ');"><sup>22</sup></span> A PRIVATE PATH … FOUR CUBITS. A Tanna taught: Others say [that the path must be of such a width] as an ass with its load may be able to pass. R. Huna said: The <i>halachah</i> is according to the Others. The Judges of the Exile<span class="x" onmousemove="('comment',' Samuel and Karna. ');"><sup>23</sup></span> say: [The width is to be] two cubits<span class="x" onmousemove="('comment',' Gomed; V, however p. 279, n. 6. Others consider the gomed to be shorter than the cubit by a hand's length and to represent the distance between the elbow and the fingers. ');"><sup>24</sup></span> and a half; and R. Huna said [that] the <i>halachah</i> is according to the Judges of the Exile. Did not R. Huna say [that] the <i>halachah</i> is according to the Others? — Both measurements are identical.<span class="x" onmousemove="('comment',' Lit., 'this and this are the same size.' ');"><sup>25</sup></span> A PUBLIC ROAD … SIXTEEN CUBITS. Our Rabbis taught: A private path<span class="x" onmousemove="('comment',' For one person into his own field. ');"><sup>26</sup></span> [is of the width of] four cubits; a path from one town to another<span class="x" onmousemove="('comment',' Reserved for the sole use of the inhabitants of the two towns. ');"><sup>27</sup></span> [is to have a width of] eight cubits;<span class="x" onmousemove="('comment',' To allow two wagons to pass each other. ');"><sup>28</sup></span>
Jerusalem Talmud Kiddushin
In R. Eliezer’s opinion, the rules of acquisition of a Canaanite slave are not identical with those for real estate; he will reject deriving legal rules from a verse in the Prophets. If one walked across a field in length and breadth, he acquired up to the place he walked to, the words of Rebbi Eliezer. But the Sages say that he did not acquire up to the moment he acted in possession345He performed some agricultural work on the property.. Everybody agrees that if somebody sells a path to another, when the latter went, he acquired. What is the reason? “Arise, walk in the Land in length and breadth, for I shall give it to you.346Gen. 13:17.”
