R’ Yehudah says: This is none other than the wall of a vineyard. But what is the perimeter of a vineyard? Between two vineyards. What is a wall? [That] which is ten handbreadths high. And a ditch [is that] which is ten deep and four wide.

A partition of sticks — if there are not three handbreadths between one stick and the next, enough room for a goat to enter, then this is a partition. A wall that has been broken — up to ten cubits, this is like an opening; more than this, it is forbidden [to plant] opposite the breach. [If] many breaches have been made in it — if the standing [part] is greater than the breached, it is permitted. But if the breached [part] is greater than the standing [part], opposite the breach it is forbidden.

[If] someone plants a row of five grapevines — Beis Shammai say: [It is] a vineyard. But Beis Hillel say: It is not a vineyard until there are two rows there. Therefore, [if] someone plants [within] the four cubits of a vineyard — Beis Shammai say: He has condemned one row. But Beis Hillel say: He has condemned two rows.

[If] someone plants two opposite two, and one protruding like a tail, this is a vineyard. Two opposite two and one in between, or two opposite two and one in the middle, is not a vineyard until there are two opposite two and one protruding like a tail.
