A BIT MORE
1. In the times of the Mishnah, "a place to make a grave" did not refer to a single grave. Rather, they used family burial caves with burial compartments in the sides of the cave.
2. Such a cave is 4 by 6 Amos (Tosefta: with a height of 4 Amos). It has 8 graves in the walls, 3 on each of the two opposite walls, and 2 on the back wall (with the fourth wall being the entranceway).
3. They must be 4 Amos long by 6 Tefachim wide, and 7 Tefachim high.
4. He understands that it should be 6 by 8 Amos, with 13 graves in the walls.
5. However, there is a dispute about how many burial caves are included in an agreement to build "a place to make a grave." The Tana Kama says that two caves are included in this agreement, while Rebbi Shimon maintains that four are included. (Everyone agrees that these caves share the same 6 by 6 area.)
